Is a jack plate the answer?

[Tacklewasher]

So I have an issue with my prop ventilating and I also want to use a jet leg at times on this motor. So I need to lower my motor for the prop and raise it for the jet.<br /><br />Understand I converted this boat from a OMC Stringer I/O to an outboard and missed on the transom height calculation. So to get the boat working better with the prop, I would have to cut the transom and re-work it a bit. <br /><br />I also run this boat in the Fraser River and have bought a jet leg for that use. I plan to swap to the prop in the spring for the lakes and put the jet on in the fall for the river.<br /><br />One option I am thinking about is to get an extension for the motor and raise it to the proper height (maybe 3 inches). Then I would remove the extension when putting on the jet.<br /><br />But I'm wondering if a jack plate would work as well. It would have to be adjustable and I'm concerned about the extra strain on the transom.<br /><br />So, any ideas one way or the other?

A Bob's convertable jackplate would give you several setup options.

Tacklewasher, just for interest sake, why not keep the jet on for the lake as well? Whats the reason for going back to the prop drive? Better performance?<br />Wish I had the option.

Better performance, better gas mileage and not having the jet wash when I am tubing/skiing.<br /><br />I'm told to expect about 30% drop in top speed from the jet. I will gladly give that up for cruising for salmon in the Fraser, but would want it back for summer fun.
