[RiverRacer]

Well, I don't remember that but here goes, if the bottom is flat fore and aft set the plates flat with the bottom in the center, left corner 1/16" up right corner 1/16" down and a 1/16"-1/8" gull in each plate!.. BUT, unless the bottom is free of discrepencies and the power, prop and gear combo is right so it can take a set, plate settings are pretty much worthless!...

[poncho]

Thanks Art i was looking fot that too,dosent hurt to try u know

[RiverRacer]

Never know until you try!..;)

[hm66Howard]

Thank you Art. That comes in handy. :)

left corner 1/6" up .

Is That 1/16"??

[RiverRacer]

Is That 1/16"??

Yep, just fixed it!..:D

[kostelacd69]

well im going out in the morning so well see how it goes

[RiverRacer]

Good luck and be safe, let us know how it turns out!..

[kostelacd69]

well the boat works real well when the water chopy but after it calms down the boat just porpesis if you add nickels it get worse if you add weight in the front it gets worse trying to figure out what to do with the prop rbr just cut it its now a 11 1/4 x 15 1/4 any ideas

What gears you got?, I'd be trying a different prop, take the nickels out and borrow some props, if you got the gears a 10 3/4x16 would be a good start, but even an 11x15 would be better!.. How much travel you got in the plates and how long are they??..

[kostelacd69]

ive got 28 in it right now but i ahd 15 in it too and did the same i put bills prop on it that was like 11 x 16 seem alittle better but still did it

[RiverRacer]

Looks like you have issues alright, how long of plates you have and how much travel?, what's you're shaft angle, also how much power you got??...

[kostelacd69]

i had 5.5 inch and know ive got 10.5 inch plates 550hp angle is 8 degres

[kostelacd69]

one inch of travel

[kostelacd69]

im going to cut the strut and the shaft an inch and see what that does

[RiverRacer]

i had 5.5 inch and know ive got 10.5 inch plates 550hp angle is 8 degres

Ok you just made it worse, what you did by extending the plates is move the prop 5" forward, and that's a huge amount and that lifts the nose big time!.. Eight degree angle is good!..

[RiverRacer]

one inch of travel

That's good!

[RiverRacer]

im going to cut the strut and the shaft an inch and see what that does

Now you're really going to screw it up, that will move the prop even further forward and make it even worse!..

[kostelacd69]

yeah i exstended the boat 5 inches and that makes it think that its 5 inches longer but how is that bad if im cutting the shaft another inch moving it forward another inch

[kostelacd69]

but if i push the prop back it gets horrible

[RiverRacer]

yeah i exstended the boat 5 inches and that makes it think that its 5 inches longer but how is that bad if im cutting the shaft another inch moving it forward another inch

Because you're moving the prop forward and that lifts the nose!.. How far is the motor from the transom?????..

[RiverRacer]

but if i push the prop back it gets horrible

Moving it back lifts the tail and drops the nose, you have other issues!. I think it's time to start from scratch, too many changes and nothing works, you have to one change at a time!..

[kostelacd69]

29 inches all the changes that ive made were one at a time going to the lake and playing with it and the plates all day this was all last year bill and rbr are saying that the problem is is that the nose isnt getting lifted the back is theres not enought lift on the front of the boat thats why when i add weight to the front it doesnt help and when i move the prop back it gets worse its lifting the back to much

[RiverRacer]

Should be more like 34", if it lifts the tail too much then it will nose dive not hop. Have you checked the bottom at all for hooks or rockers???..

[kostelacd69]

well the hull it self has a rocker in it about 1.5 to 2 feet from the transome the bottom isnt perfect but no hooks

[RiverRacer]

Yeah that's tipical when a motor sits in it all it's life, it develops a sag over time!.. Bottom should be fixed!..
