Motor issues

[shakey head]

Thanks for all the replys…. I usually do start trimming the motor up as the nose starts to fall I always have but it doesn't want to start to fall.... But I'm taking the boat out this weekend and I'll try to trim it earlier and see what happens....

Also sorry it's took longer then I thought but I got the measurement of 3.25 for pad to prop that is close to the measurement that was suggested

Ok so it ran fine for five or six trips. I think that's where we start. By shifting weight and motor height you are probably masking the real problem by reducing the power necessary to get up on plane.
You shouldn't have to alter how you were driving it to get on plane again hat just shows you that its probably engine related. I to had powerpac issues on a 150 Merc. Had them replaced and what a difference. What was interesting is that the motor was smooth no missing just loss of power under heavy load. Unless you find hat for some reason the trim has shifted dramatically I would take it in to a service tech and have the engine checked. My Mercury cost me 450$ about 15 yrs ago but was well worth it .
