Annoying Porpusing.........
 

Has anyone experienced the bow of their boat nose diving to the left under acceleration? Its a SS8M with a single BB Chevy. Just started doing it after installing a new engine. It made almost 700 F/P torque so I assuming thats the problem. It is also porpusing after 60 mph which it didnt do before. Both problems are very annoying and I need some advice on how to correct them......Thanks.

have u talked to throttle up yet?
are your tabs even?
You may want to post this in the general forum to get a better response.

Thanks Stormrider, I will do that. :ernaehrung004:

Prop work ( throttle up ) or raising the drive it self !!!

I had put a call into BBlades. Dont mean to put you on the spot, but who do you prefer and why? PM me if you want. Would a shorty work instead of raising the drive? Prop work would stop the nose diving? Thanks for the advice.

ThrottleUp is no longer doing prop work on any props except
their own Throttle-Up in house made props,
at least that is what Julie emailed me.

Sounds like your drive is too low in the water.

Yes,,,a shorty will work ,,if u have a Bravo ??!! DO YOU ?

Yes , its a bravo 1. I think I will start by talking to someone about the prop first. Hopefully getting the nose diving situation taken care of, and then focus on the porpusing. Even trimming doesnt stop it. Im taking it out today and adding fuel to the boat. Only had 1/4 tank of gas when I tested it. Maybe more weight will help ?

Nose diving ,,kind of is porpusing !!!

Prop may help a little ,,but i think your drive is way to deep.

Let me guess , propshaft 6+ inches below hull ??!! right ?!:rolleyes:

What prop are you using??
