r/Outboards

I’ve got a 1996 Yamaha 85CV, lower unit started to make a bit of noise so I dropped the oil. What came out was 99% water and then a few drops of oil on top at the end. Amazed it still functions well and not too much metal on the bolt. Topped it up, will run it for a few trips and then check it again.

Given that it’s full I figure it’s the seal at the shifter that’s the likely culprit.

Last year my outboard ran alrightt after i got it and fixed it up. after i took it out of winter storage i couldnt keep it running. So i cleaned the carb because i had left gas in it so i probably had some clogged jets. The problem im now having is that it runs but only when i give it gas. Im thinking that i did something wrong and eventually stumbled on maybe i should adjust my carb but where is my stationairy screw. If im missing it where do i put it in? The brass screw in the first picture on top is something like picture 4 and gemini says it should be tightend until it doenst go further.

Anyone know where can find an aftermarket carb for this motor. The original one from Honda discontinued. Thanks

Johnson 25 HP doesn’t start. Opened it and found this lose on the floor of the box. What is this and where does it go? Chatgpt showing all kinds of answes

This part of carburetor is broken, will it prevent it from turning on? Its my first outboard motor been trying to turn it on and it turned on for a sec then it stoped.

Anybody have a clue to what kind of outboard boat motor this is I can’t find that symbol anywhere and there is no model number or serial number on it any help would be great

Hey guys!

I recently bought a 1960's 6hp for only €75! Im trying to get it to run, fixed some electrical issues and got it some fresh plug. Wasnt getting any fuel so i disasembled the carb and cleaned her out real good (sadly has a corc float). After putting it back together i notices alot of fuel just chilling in the air inlet. Anybody knows why this is happening?. I got her to run yesterday so i know she got life in her. When i tried to get her to start today she popt off maybe 10 rotations and then dies, and wont start again. She is somehow running waaay to rich. I have worked on alot of yamahas but this is my first time with a evinrude. Any help is welcome!

I have a 2001 Johnson 15hp 2 stroke that I recently removed from my boat. I’d like to be able to start it for a potential buyer, but I reused the controls so it does not have any. I’ve done some research and it appears I need to locate the 12v+, run and ignition wires in the harness and tie them together then I should be able to jump the starter solenoid to fire it up. Obviously I’d also have the battery cables connected.

Can anyone confirm the wire colors for the motor? I’m getting a little conflicting info online, so thought I’d ask. What I believe is correct is: Red/purple is 12v+ Purple is run Yellow/red is ignition

What about neutral safety switch? I’m sure I have to connect 2 wires for that as well, right?

I’m completely new to boats, seller said it ran great “no issues” so I just thought I could take it out same day. Which I did and just so you know I’m new to boats and I guess I blew the middle piston “0” compression. I got this boat for 500$ bc I’m on a budget. It floats and all electronics work, even the night lights. If I wanna get back on the water should I get the block honed and put bigger pistons in? Or should I just get a new motor?? Best thoughts!!! Please help!:((?!!!! ALSO I FOROGT TO MENTION MY BROTHER HELP ME GET OFF LOWER PUMP AND WATER IMPELLER WAS COMPLETELY GONE. I’m guessing that what caused it to blow.

I have a 2001 Suzuki DF70 (came with a cracked lower unit case) with a 2004 DF70 lower unit, I bought this lower unit used, and unfortunately it had a bent prop shaft (1/16” runout), which wasn’t disclosed. So I put a new shaft and seals in, put it together and in gear it makes a bit of metallic rattle. I cannot recall it making this noise before but I haven’t run the motor much on muffs.

I have checked for play axially and found it to be within spec (no fancy tools but it barely moves), radially it feels like it moves ever so slightly side to side but there is no runout of the shaft that I can see when running without the prop. It only makes this sound in gear, it is louder in reverse and only happens with a prop on. Prop off and it is smooth as can be.

I have begun taking apart and rebuilding an engine for the first time. It’s an older (2003) Merc 50hp 2-Stroke. Before disassembling it had low compression across all cylinders (60-70 across all 3) verified with two separate compression gauges. I would start and run; however, seemed to have excessive oil in the exhaust and ran a little hot. The prior owner was not a real maintenance kinda guy and I don’t think the impeller was replaced often and I stupidly did not verify the oil injection pump was working before I disassembled the thing (too late now).

Split the block and didn’t notice anything super alarming like loose metal bits or anything. There appeared to be a little bit of very light discoloration on the surface of the block towards the first cylinder as well as discoloration on the pistons which I figured was a result of blow-by of exhaust gas (see photo). I have yet to measure the bore diameter but there was a bit of vertical scoring that was deep enough to catch a finger nail on in 2/3 cylinders.

As this is my first time I am really looking for any and all advice on next steps or reference materials to consult. Thanks!

How am I supposed to get this lower pin out so I can drop the lower unit to replace the impeller?

I tried tapping it lightly with a thin nail but it is in there pretty good and I didn’t want to bend the shifting linkage

Tohatsu 9.8 -~2014

Hey guys, I have recently got my hands on this beautiful 2 cylinder Chrysler 45 from 1975 that has been sitting for at least 10 years, if not more. I cleaned the carb, changed the spark plugs and it starts and runs like a charm.

The problem is that while on land the engine is able to reach max rpm, but in water it struggles. The boat reaches no more than 5-10 kmh and there is no difference in engine rpm whether it is half throttle or full throttle. So in water in gear the engine feels like it can reach only half of the rpm possible.

Do you know what could be the problem and where to dig? Thanks

Just bought this engine. When I give it throttle it does this and it makes a scary sound and revs up very high. Is it a spun prop?

Hey guys, looking for some advice for our lobster boat running twin Yamaha 300HP V6 4.2L outboards.

What prop size do you recommend for the best balance of power, speed, and fuel economy?

Thanks !
