I would guess they are too low...if I was sure the props were right. The more gear case in the water....the more slip you will have. What kind of psi are you seeing??

did you say you didnt trim it up???

the best thing you could do would be to contact Jay at Spectre give him your hull number and he'll be more then happy to go over everything ith you. or find someone around you that knows the boats. i have no tab on mine, come on plane with engines fully tucked with no problem, and only trim up approx 2 notches...4 notches is neutral so my boat isnt being trimmed much at all...dont go and start buying props yet, make sure engine heights are correct, toe is correct etc before ya go spending money. if it comes to props i have a brand new VIRGIN unlabbed 15x32 and a labbed 15x32 that i'd be happy to sell ya if my boat sells.

Does anyone have Jay at Spectre's phone number? Is Jay the original owner/designer of Spectre boats? Does he still own it?

Engine height and props are the problem. 14.5 is too small. 15x32 Mercury Labs is about right. Make sure you get Lab props. Gearcases may too low since the rpms are low and slip is high. Slip ratio 21%+ is way too high. You are on the right track to getting it right.

i like the way the 14 1/2 x 30's feel on mine less strain on plane and mid range is better but i also have 300x's...unsure if he has plain 300's or x's. the 15x32's were a better top end prop but could only spin them to 63-6350 rpm's with the 14.5's in the chop i'll tap on the limiters occasionally...

I've got the 300 Promax, NOT the 300X.

I've got a call in to Jay at Spectre. Hopefully, he can get me on the right track.

Any other ideas?

never trim a cat above ... level with the bottom.....or ELSE your going to get hurt.....

Another thought I just had, the boat was always ran in Salt Water. I'm wondering if I should tuck the motors down more? Would that get them to hook up better?

Anyone know the rev limiter on 300 Promax's?
