ok.... first had the problem with the rpm/mph. changed props from 14 1/2 x 19 to a 15 1/2 x 15.. only because thats what the prop dealer recomended, probably because he wanted the sale an didnt have the 14 1/2 x 15 that i asked for. current problem.... installed the prop an works great im running somewhere between 4200 rpm and 4500 rpm at around 30 to 35 mph ( forgot the gps in my truck) but now after about 5 mins or so the boat started over heating. i pulled the bottom hose an put some back pressure to maybe blow out any clogs an putted back to the slip at a relatively warm temp. so my question is could the prop be the cause, or maybe coinsidence. impeller in the water pump, or water pump gone bad? any info on personal experience or current knowledge would be very helpful.... on a side note... does the alternator on my boat actually charge the battery or do i need an auto trickle charger?
