Hello all, nice to see everyone enjoying their boats this season. Great pics BTW. Ok, my issue is after I replaced my water pump because it was leaking last season I didn't really notice the rust the salt water leaking from it caused. After my last outing to the sandbar I opened the engine compartment and my serpentine belt was beginning to show wear(white on one side) and it is new (only 3 hours on it) Upon further inspection I noticed that I had rust on my idler pulley,circulation pump pulley,power steering pulley, belt tensioner pulley, and alternator pulley. My question other than replacing them all to the new volvo penta parts has anyone used any aftermarket pulleys like the ones on those go fast boats( the shiny ones ). I figure it should be a straight forward repair just loosen the bolts and replace the parts for new, any insights on how hard this project might be would be very much appreciated. Thanks in advance for any input. 2008 H220SS 170 HRS 5.7 GXI 300HP DP

I have sanded & painted my pulleys with a brush on, anti-rust paint in my engine's color.
Has worked a treat for 50+ hours of use...

I will take a look at them again and see if their salvageable, will save me quite a bit of money if so because these parts can be pretty expensive.

I wouldnt replace the pulleys you can sand and repaint them . or if you know someone with a sand blaster . the only one i would be concerned about would be the idler pulley. if it spins smoothly it also can be cleaned up but not sand blasted

Which water pump did you replace; the raw water pump or the engine recirculation pump ? If the latter, I'd check the pulley alignment as well; that can affect belt wear. I changed one on a previous boat, the replacement one had the flange onto which the pulley fits pressed further down the pump shaft than it was on the original. I used large washers as spacers behind the pulley to bring the pulley back in line with the others.

Glad I asked the question because everyone is telling me to sand them and that is definitely cheaper than buying them new. The idler pulley spins smoothly, glad you mentioned to not sand blast them because I'm removing them and dropping them off at my local machine shop.

Replaced the raw water pump, it was a pretty simple on and off procedure also inspected the pumps side by side and they were identical.
