Author Topic:   Engine height on 13' BW

I recently bought a 1987 13’ SS with a 2000 40 hp Johnson.
I think this engine is mounted too low. Cavitation plate is slightly below the bottom of the transom.
I thought that it would be better if raised so that the plate was even, or an inch or so above the bottom of the transom. Looks relatively easy to do.
Anyone have experience with what mounting height performs best overall?
Do they run better with a “doel fin”, or other hydrofoil?

As mentioned frequently, the typical engine mounting height on a Boston Whaler is in the second or third hole, putting the anti-ventilation plate an inch or so above the keel centerline. You will find much previous discussion on this.
