    2001 wellcraft 270 costal powered by a mercruiser 7.4 mpi with a bravo 3. Doesn’t accelerate.

    Thanks for your thoughts. To the naked eye what will the clutch look like if burnt? I read that I can look shiny. Thanks, I will take the clutch apart and find out what’s going on. I read that the clutch can have a shiny glaze when burnt. Is this true? Also where the clutch engages with the...

    Ok, Last weekend I took the boat out for a test drive to narrow things down and I noticed when I slowly back the throttle off to 2000rpm. I get a sudden vibration that last about 5 seconds. Can it be related to the clutch? Narrowing my problems - not the coupler - possibly the cone clutch

    I was thinking and thought can the lower shifting cable not be adjusted properly causing the cone clutch to slip under load ?

    Thanks, I’ll check the problem out once I pull the boat out. I really hope that’s my problem.

    Ok, would I smell the burnt fluid or will I see the damage on the cone clutch? If so should I just replace it?

    I knew I should have changed that seal. Would I be able to run the boat like this for the rest of the season? Lastly would the burning of the cone clutch cause the boat to delay shift into gears because the boat shifts into gear instantly only thing is I get a slight knock going into forward...

    Hi, Scott For the past 2 months I have added a quart of gear lube. I always kept the reservoir topped off. I asked a mechanic about it but, he said it could be a seal and I can change it next season as long I kept the reservoir topped off. I think it's the upper seal because I can see the...

    2001 wellcraft 270 costal powered by a mercruiser 7.4 mpi with a bravo 3. Doesn’t accelerate.

    Yes, The splines are built with the prop and they are in good shape. How can I be sure it’s the coupler ? I tried full throttling it and the max rpm is the same are before it sits around 4500 -4600. I would think the rpm would go higher if the coupler is slipping. Don’t you think? These are...

    That was a thought but, no burning rub smell and feeling the coupler the rub had no broken pieces. Also I would also think that the coupler will fail or work due to it being rubber once spun out always spun out. I was thinking if my hull has grass but I’m not sure if that would have such an...

    Hi everyone, I have a 2001 wellcraft 270 costal powered by a mercruiser 7.4 mpi with a bravo 3 prop pitch 22. This summer the boat ran great no issue at all coming later in the season I noticed that at 3000 rpm the engine will rev to 3200 rpm on its own and gain no speed. When that happens I...

    Mercruiser 7.4 mpi

    Thanks for all the help everyone, I found the problem behind the engine upper left there is a oil pressure sensor. In my case the ground wire was loose. In other cases it can be a bad pressure sensor. Soon as I secured the ground she fired right up.

    Mercruiser 7.4 mpi

    I didn’t try starting and looking at the live data. It as a bravo 3. No number with the code. The scanner I got is a techmate pro. Also I am only seeing the oil pressure sensor with the single wire on it so I believe you’re right.

    Mercruiser 7.4 mpi

    I cleared the code but it’s still coming back I can getting 40 psi at the gauge when I turn the ignition on. Can this be the reason the engine won’t start on its own?

    Hi, I got a scanner today and I’m getting one code. This is the code “Low oil pressure telltale has been set”. Does anyone know what it means?

    Mercruiser 7.4 mpi

    Hi, yes i forgot to mention I changed the ignition coil, distributor cap, rotor I changed the plug wires last year. Also I started the engine and I didn’t change the plugs because I was waiting for the fogging gas to burn out. Since I was having the same problem I changed the plug and found...

    Mercruiser 7.4 mpi

    Thanks for the reply. I know the fuel pressure is a bit low but why doesn’t the engine try to at least start. I added gas in the filters and the tank. Are you saying I need to change both regulators?
