This boat is going to drive me nuts! Had a mechanic kindly nuke a motor for me so I now have a new motor but same dang problem.
16' high tide flats boat
Yamaha 90 sho with a prop tech 18p four blade.
20 gal fuel tank up front. Group 31 tm batt and a motorguide wireless.
Console has a group 24 under it
Smart tabs
So by myself I get about 38-40 mph but when you get the trim about right and the spray at the console it will porpoise with any movement. I cant ever get a decent ride. Motor is mounted in the top hole but the cav plate is right at the top of the cut out. I'm getting 58-6000 rpm. I've tried a 17p alum 3 blade, 17p/3 blade, 19p/3blade and now the 18p/4 blade which will get that rig out of the hole fast enough to snap your neck. I'm just not sure what the heck to do with it. I'm being told it should be running a lot faster.
