Finally got my 18' is at the shop (H20 Marine, Sarasota) and this week to have the transom cut. Going to remain on the lower end of the food-chain and stick with the Alpha drive, at least in this incarnation.
Decision time on the X-dimension. Donzi says '14.5 inches' is standard and recommended (thanks for the same afternoon response Bryant, now that's customer service!). Mercruiser says 22" (trusting memory) vertical height for most SBC. I want to keep the engine hatch uncut (no scoop added), so engine vertical height will be the limitation for 'X'. Shop is recommending minimal increase from the 14.5" recommendation.
NEW twist...we have decided that while noise is good, we can for see there would be times that quite would be desirable and will likely end up with a Silent Choice or similar. It appears these systems typically fit within the vertical profile of a SBC, am I right on this??
Someday would like to install a 350(build-up or crate) to about 300HP with Stainless Marine mfld/risers, Silent Choice and still keep the flame arrestor under an 'original' (uncut) hatch.
With all that in mind, what do you say experts: "X dimension should be ___?????????????????"
The cut is planned for the beginning of next week.
