Ideally you want the vent plate about 1-2" above the bottom of the transom (depending on prop). So looking at your ruler I think you need to lift at least 2.5" and I would think with two holes left you only have 1.5" to go.

Can you take a picture of the transom from the inside showing engine position. It may be you have an XL shaft on a 21" transom which would explain your issue.

i have just had a look at the vin plate and the leg is UL (i m assuming that ultra long) looks like i may just have to put up with the splash. although i could try it on its highest setting

The transom is 22" so it is designed for a standard 20" Long shaft.

You may be able to change out the leg and drive shaft for a shorter one. You'll never get the best performance out of an Eagle with the bottom of the leg buried in the water. Definitely worth looking at ways to resolve.

As well as splashing you may well find that the RIB tends to lean to port and also your fuel consumption will be higher and your speed lower...

the outboard is a contra rotating unit offset to port and it seems to run true and straight.its topping out at 39 knotts on flat water.any idea where i could get the parts to convert it to a shorter leg its a 130 yamaha v4. what about a jack up plate from america although im not sure i like the thought of that

a 130 Yamaha (guessing its a V4 2 stroke) should push that Eagle to 45 knots.

With your engine being mounted to port already it will need to be a Contra rotating one which wont be easy to find, although ebay would be a good place to look. I should imagine its the same leg as a 115 and possibly 150 however don't quote me on that.

All depends on how far you want to go. If it were me I would source a longshaft standard rotation, remove the engine and fill the holes (properly) and then refit the engine with some starboard offset.

If you are comfortable doing this yourself you should be able to find the parts to do all this and then hopefully manage to sell your XL or UL shaft parts to recover most of the cost..

A nice winter project perhaps !.

This is a useful resource for looking up parts and seeing what other models the gearboxes were fitted to.
