ICE Ratio is stamped on the inner casing or you could put a mark on the output flange turn the prop shaft one revolution and see where the output shaft finishes

I will get you those details tomorrow and some photos if that's ok.
Previously had some experience with the Russian Tv3 and French Turbomeca Turmo. In fact, I have some Turmos for sale 1600hp with a reducer gearbox built-in they have an output shaft speed of 6000rpm if anyone is interested.
Any idea why the BPMs are so hard on props? driveline doesn't look any different to say an ASD8 the only thing I can see is that would possibly cause this is the N2 lag if the prop leaves the water as the N2 doesn't decelerate as quick as a gas motor would.

Didn’t 302sport have that nor tech over here not long ago?

Ok managed to get you some dimensions today.
The transom is around 4 degrees and running a straight edge through the centre of the drive the trust socket bottom is around 1" higher than the running surface

He bought it in Europe, and then jay had it shipped from Europe and said the boat hasn’t been run in years. So I wasn’t sure if it was shipped here, not used, shipped back to Europe also not used and now back in the states or if it never left ?

The boat is in Europe at present and heading back to Florida next year,

I was just affirming your history of the boat in the previous post with his own quote.... always interesting to hear the actual history of certain boats that go off the radar

thank you so much for the info and pictures!!
One more question if I may in the running surface picture you showed me with the level,
if drive was trimmed all the way down how much would the casing right behind the prop be under the running surface?
The Skater runs a 16 degree transom so its designed for a Sterndrives.
I had to configure the bpms with wedges to run close to that 4 degrees. John Coskner confirmed mystics 50 is 4 degrees also.

I could start a whole bpm conversion thread
