1995 OMC Cobra 5.0 EFI changing alternator

[irish70]

I have a squeeking noise emitting from alternator and smoking belts. When I run at low RPM's for a few minutes then I can run it up in RPM''s and it won't squeak or smoke. So I'm planning to pull alternator. Does anyone have pictures or explanation of a good way to remove. With the bulk head so close, not a lot of room to visualize. Thanks,

Access to the engine compartment is not easy on some boat designs, they're all different depending on seating ect. Some you can just pull the engine cover and everything is right there and others you have to spend half the day pulling seat bases.

Can you post a picture so we can help you better? On my boat I have to only pull one hose off and it is completely accessible.

Before you change the alternator, run the engine and carefully take a small wire brush and ride it into the "V" groove of the pulley on the side without the belt. Mine did the same thing and was caused by rush/corrosion on the pulley. After you brush the extra off, take some WD-40 and lightly spray it protect the metal. Worked on my ford 5.0 (OMC).
