Jacking plate

[jonp]

Not for a rib as my rib runs very well as it is but interested to know form those who have actually used jacking plates. Like any product for sale the advertising sounds like they can help make several improvements. Not that my non rib doesn't perform well but Im keen to see if I can get get a bit more from it. Its a 17ft hull with a 140 Suzuki 4 stroke, which aren't the sprightliest of engines.

Any first hand users with negative results from using them ?

I have a manual one. 5.5imch offset I think. I used it to gain an extra inch or so in height and set prop back further into clean water as it used to over rev when going on the plane. The prop is very high on stepped hull but I gained more grip and maintained my same speed despite adding maybe 250kg.

The disadvantage is the offset rear puts steering ram on top of transom so I can only tilt up about half way and the other disadvantage is all the extra bolts and lumps of metal could fail. I’d much rather it was on the transom but I wanted a fast rib too.

Really?
Perhaps an extra '0' has crept in there.

No. Completely changed layout and significant structure. Easy 150kg added and moved weight forward.

Performance issues are common and nothing to be ashamed of. Maybe your "friend" would benefit from a Jack Plate as it will compensate for his paucity of LOA and va-va-voom?
