My 01 TR20 with 225 rude ram would jump right up on plane when I first got it,then I started fish heavy weed beds & it would have a proplem with bad blow out woulded get on plane,could'nt figure out what was going on,took the prop off to clean shaft & found that weeds were getting caught up behind prop,there is around a 3/16 gap were the prop is a smaller dia. than the lower unit letting weeds get wraped up behind prop causing the exhaust to blow out the gap, My merc had a tight fit to the gear case,is this the wrong prop on my boat?It is a 13 1/2 X 25 renagade bass,this is a real pain in the a$$ to remove the prop when I idle threw some weeds it happened agian today & i was only in the weeds very little had to take it off & pull out a hand full of weeds!This has to be causing the blow out.Any ideas on this Help!
