OK, well I can’t imagine why you would have to modify the sensor coil clamps, the one clamp that I saw looked like the correct clamp…Will not argue with success though…
These engines are pretty cold blooded until they warm up, and the turbo jet set up probably doesn’t “load” the powerhead the same way the old outboard unit did, exhaust back pressure is different also. Does it idle OK once warmed up? I would put the rig in the water and try it before getting too concerned. Did you drill the heads for the oultet nipples? Looks like that exhaust elbow relies on some of that water to help cool the exhaust.
Finally, please remember that this engine does not have the oiling system, so you will need to advise the new owner, perhaps put some sort of placard near the fuel fill. It is easy to understand how easily it could be to “asssume” this rig has oil injection and ruin the powerhead quickly….
