Thread: Need a really experienced

Torch, 11" under the pad is insanely low. On my boat, if I take my jackplate and run it to the bottom, I get crazy long plane times and it will actually overheat the motor due to low water pressure. I think you've jiggled and shifted so much you've gotten way outta whack on the initial starting point. Take it back to a decently low starting point, record your numbers - Pad height, rpms, pitch and make on prop and performance characteristics and get that info to a real prop guy for advice. Re-run with his suggestions and report back to him for further guidance. Only real prop guy I know is Rich Boger, but I couldn't find a website on him. There are others, but I can't recall them by name. You can probably bang around some bass sites and get some names to try.

Here's another source Torch. DAH. These guys make a living doing props and only props. When you hear of Kevlar Hulled Bullets pulling runs of 112 mph, there's decent a chance there's a DAH wheel on the back getting it done.

Rich Boger is known for custom work to pull heavy sleds to new highs...Ranger, Triton, BassCats, but also does his share on the go fast boats too. Just can't seem to find a website on him.

There's another guy I've heard of mentioned on several boards - Mark...often mentioned as in "A Mark's custom prop" or "custom worked by Mark", but I'm not really sure who he is. Found a site called Mark's Custom Props, but don't know if that's the same guy...but apparently, he's legend on performance too and that's all he does if you can figure out which outfit is his.

With your calculations it is 47%

Went to lake yesterday and moved motor all way up.boat jumps out and is faster to half throttle. When I stomp it down it pushes the bow down and I cannot trim any more

Is it possible that on your particular boat and hull design that the jack plate might actually be working against you by having your motor too far behind the boat?

G I put shims to handle that

Bow lift = Cup.

Looks like you're gonna need a prop man. Or at leasta prop man that can tell you which make and model will give you the best lift.
