Alright, boat is a 1993 Four Winns H210, with ~760 hours on it. A few weeks ago I put a new SS prop on it and took it out for some hole shots and top speed runs. Get down to the end of the lake and slow down to turn around and am assaulted by a burning rubber smell. Get back to the dock and see the alternator belt all glazed up and shiny, burning hot to the touch. This is July 3rd, beginning of our vacation week, so I overnighted an alternator from West Marine, which arrived July 5th. I installed it myself with really no issues; dash gauge lit up around 14v, hooray!
Couple days later, out horsing around in the boat, and the burning smell is back. Sure enough, brand new belt is all glazed up and burning hot, belt dust all over. Dash gauge was reading about 12v while cruising around 2500 rpm. Meanwhile, the powersteering v-belt, which shares the crank and waterpump pulleys, is cool to the touch. What is going on??
Old alternator was a 3-wire Prestolite, original to the boat, with orange, black, and purple excite wire.
The new alternator is a Sierra, purchased from West Marine. Didn't take a pic but it looks just like the one I uploaded. I've been reading something about adding a jumper wire between sense and B+? Any validation to this? Why wouldn't the original alternator have had that?
Our pulleys are a little rusty but I kind of think there's more going on here. Might also be worth noting since this issue has arisen, the boat is a complete DOG; it can't get out of its own way. It'll get up to top speed of about 49-50mph, but getting on plane takes a recklessly long time. (Could also be that the entire ignition system is original to boat too; just ordered all new wires, plugs, cap, rotor, coil to put in soon).
Any insights would be much appreciated!! Thank you in advance.
