I would use a riser on your transom for your jet height. Some variables setting a jet. If your running a tunnel you will need a higher transom. For my 1648 50/30 jet. Have a 22" transom no tunnel.Would anyone happen to know exactly how high the transom on an allweld boat needs to be with an 88SPL with jet?
My tunnel hull not sure what my transom height is exactly on that. 1654 with 90/65 jet.
Would think 27 could be close. I will try and get a measurement.
