‘Yamaha’ 15hp outboard lower unit from AliExpress… how bad are they?

Yes yes I’m hanging my head with shame.

But.. bought a second hand 15hp 2 stroke Yamaha (15FMH) outboard and the lower unit has not been loved and is really in a sorry state all round.

Whilst I’m adding up all the parts and time I’m going to have to spend getting it back up to condition, I had a little browse on AliExpress. I can pick up an entire lower unit for really not a lot.

I get they’re not OEM quality but this motor will be used infrequently and very much looked after between uses. Has anyone had any experience buying complete lower units from Ali? How bad are they? I wouldn’t even mind pulling out the whole prop unit from the current one and slotting it into the new one if it’s the gearbox/bearings that are the weak point.

Experienced views welcome. Yes I know you get what you pay for but I’d like some real life pointers on what I’m likely to receive. Thanks in advance 🙂

Help

Bought a boat and the trim doesn’t work, bought a new trim assembly but can’t get the lower mounting rod out. Someone else worked on it and drilled into it and now I’m unsure if it’s seized or I need to unscrew it or what. Pumped it with kroil and wd40 pounded on it a bit, I’m obviously missing something. First boat unsure of what to do.

Questions

I'm restoring a 1977 Johnson 85hp. 85EL77S. I've removed all electronics on motor save for stator and timing plate, expensive. Everything else I've replaced harness, voltage regulator, coils, power pack. Starter bolts seemed stiff coming out so I tapped the holes out. We'll it has 1 bolt on front of motor and 2 on the side. One of these goes into the crankcase and I tapped it and flushed it with WD40 thinking it was a blind hole. The top starter bolt doesn't go into the block the bottom one does. Its the crankcase cover it bolts onto. How screwed am I without taking the carb adapter off. You can see in photo bolt hole goes into the crankcase cover.

Rehabbing a boat

Just as the title says, we're rehabbing a boat. It's a 2001 Bayliner 2452 LX. Husband is in charge of the mechanics, I'm heading up the design department. In time, I'd like to get fender covers, a welcome mat, a blanket, etc, all with our logo embroidered. But for the moment, I'm just trying to figure out where I can get new cushions for all the seating and the boat's name placed on the transom.

Where does one go to get that kind of thing done?

Also, feel free to spam me with all the fun customizable things!

Skeg brokem

Good day,

I sailed on a rock and now my skeg is gone.

Are these replacements working and would there be a fitting one for my engine because all the ones on AliExpress are 8.

Thanks for your reply!

How serious do you think this transom issue is?

I was admiring this little Boston whaler next to my project boat and noticed the crazing along the entire bottom corner (beam to beam) of the transom. I imagine it’s more than crazing and is the beginning of fatigue damage. What do y’all think?

What’s this? Cool looking boat.

I think the new Arksen 55 announced at Monaco Yacht Show.

I have a stupid question about winterizing an outboard

I have a new-to-me boat with a Yamaha 300 HPDI outboard on it. Everywhere I've seen (including the manual) says to winterize it I just need to drain it, keep the motor lowered, and oil the cylinders a bit (on top of changing filters and adding stabilizer, etc.).

However my friend who knows MUCH more about boating than I do insists that I should run it with muffs and a hose running to some antifreeze to get it in the engine and behind the thermostat, because there's no way to drain the water that might still be in the engine and it could freeze and crack something (I live in new england).

So someone give me a sanity check - does anyone actually run antifreeze into their outboard to winterize it from below freezing temps? And how would one even do that without spewing antifreeze ALL over the place?

How much longer does triton have before they get either axed or spun off?

Everything they make, either Ranger or Nitro also offers a version of it. They don’t have nearly as much publicity as other boat brands, partly because of how few teams use them.

The aluminum boat division is dead, they are all sold as Rangers now. The only people that buy them are people that already own them, and that number shrinks by the day.

Question on end of season engine winterize/ flush and wrap

First time boat owner and approaching the end of my first season. 21 ft 2016 sea hunt with 150 HP Yamaha 4 stroke. This repair shop quoted me around 900 for the work to winterize and flush and to wrap it. Wondering if that is a good deal? Also mentioned I should run the thing dry of gas before hand, and I should remove the battery, does that sound correct. Live in the northeast.

Changing sportfish yacht props to trade top speed for fuel efficiency at cruise speed

Hey everyone,

​Looking for feedback on a Hatteras 54 with twin Cat C32s. It’s currently reaches ~45 knot top speed, but I want to optimize fuel efficiency at a 22 knot cruise.

​Has anyone with a similar heavy sportfish been in a similar position or re-wheeled to drop top-end for better mid-range GPH?

​Open to any suggestions, experience, or thoughts before I talk to a prop company.

I inherited my dads boat, is it worth trying to save it

So my dad passed away and he bought this boat and sadly he never got it in the water due to the engine overheating. I was all ready to pay to have the old two stroke motor fixed or replaced but I’ve read horror stories of people fixing up old fiber glass boats (I worry because it hasn’t been covered since he passed, my mom kind of let it sit) and now I have to wonder is it worth saving it? My mom just wanted to sell it but I mean I just can’t bring myself to up and sell something he really wanted. But I also don’t have infinite money and I am not super handy though I can YouTube a thing or two. It’s a 1989 Stratos 19’8

How to secure a tiller?

Howdy! I’ve got a 2025 Grizzly 1650 Prairie Wings with a 60HP Merc Tiller

How do I securing the motor to keep it from pivoting side to side while being trailered? I imagine I could throw a ratchet strap around the tiller handle but I worry I’ll tweak something and adjust the tiller friction lever doesn’t cut it

I’d appreciate any advice, thank you!!

Help with Fuel Bladder

This is a chatGPT image approximating what I am trying to do... secure a 100 gallon ATL fuel bladder in the bow of my Cobia 285 Open. The image isn't entirely accurate but it communicates my question..... How do I attach the harness to the boat??? A large stainless steel pad with a d-ring as chatGPT suggests sounds great... but I can't find any in nature to buy... I'd have to have something custom welded to create one (unless someone knows where to find one). I'm also hesitant to drill into the boat.... I can't thru-bolt it. I was thinking of a large pad and using 5200 to bond it.

What are your thoughts on how to secure the harness to the boat???

Please and thanks

What is this squeaky sound?

If I’m idling out of the marina it doesn’t happen, it
only happens after the engine is warm and I come back to idle. If I give it some throttle the squeak goes away. If I bump it from idle to about 1100rpm a few times it also goes away. It sounds more like a squeaky serpentine belt on a car than it does in this video. Got a new impeller and no change.

150 Yamaha VMAX Opinion/Thoughts?

My neighbor is offering to sell me his boat, it's a 1989 Wellcraft (Sport I believe) 18' with a 2000 Yamaha 150 VMAX. Hull is in good condition, only missing the cooler seat.

Only issue he's having is the boat goes into alarm once he tries to get it up on plane. Alarm shuts off at an idle back and when it's on the hose at home. Seems like once it's under load it over heats despite the steady stream.

Looked over the oil system and everything seems good on that side.

He's replaced impeller, associated gaskets, thermostats and a few other small parts to no avail. (Not sure about the poppet)

He offered to sell it to me for $3,000 as is. I know it's a boat and the troubles that come with one. I'm not very familiar with these VMAX outboards. I spoke with a marine mechanic about them and he said he sees lots of issues.

Do you guys think it's worth the gamble at $3,000? I have not compression tested the motor yet.

Looking for advice with my 2005 mercury 25 hp outboard

Alright so I have recently obtained a 2005 25 hp mercury outboard. It was used in saltwater and not flushed before years of storage, almost everything with it is decent except on the lower unit. On the top of the lower unit there is a golden sleeve that holds two seals, and it is badly corroded. I’ve included an image of what sleeve I’m talking about from online cause I don’t have a photo of mine. I’ve found the sleeve for sell as a part online, but I don’t know how to remove it from my lower unit. I’ve done research and have only found one other person asking how to do it in the past with very little information on it. The manual online says not to remove the sleeve for basic maintenance, but this is different. Has anyone dealt with this before? Thanks
