Prostar 190 Shopper
We are looking to purchase our first Mastercraft Prostar 190 for the lake. We live on a good sized lake in Maine and I am familiar with Mastercrafts from teaching water-skiing on Lake Champlain in the early 2000s. We are currently looking at late 80's 190's (like the ones I drove before) and I am wondering what are some things I should be looking for. Obviously we are checking engine compression and driving any boat before we buy it.
One concern that has come up is that all gas in NE now is 10% EtOH and we have been running it in our boats with Star-tron fuel treatment without issue, but I'm wondering if Mastercrafts of this vintage are faring alright with EtOH fuel? Also are the fuel tanks plastic, metal or fiberglass? I want to avoid any fiberglass fuel tanks due to fiberglass issues with ethanol enriched fuels. I would appreciate any advice you might have about buying a 1987-1990 Prostar 190.
