the original water pump pully on my boat was the smaller one and i am swapping it out for pulleys off of a hp500 which is a larger pulley. does anyone know what size of belts i need for this? thanks

If you are making the front of your engine like a 500hp carb motor, you can get these belts at NAPA
Alternator belt: 25-7475 Premium XL
Power steering belt; 57-812427 DF
Sea Pump belt: 4L410
This is what I run on my 500hp's

thanks! not really trying to make it look that way, well not intentionally at least. i have a few hp500 parts laying around that are better than the parts that i have on my engine such as that larger pulley. i ruined a belt at the end of last season anyways so i figure i will replace them both and use the new pulley
