Motor mounts could be replaced with carefully located wood blocks and a
porta-power or bottle/scissor jack... Or maybe get some fine-pitch
allthread and make yourself a jack of sorts
You would have to re-align shaft/coupler.
I would recommend looking at your mounts to see if you can move at all,

We do about 7 with a 3 blade maxprop and a yanmar 3gm, our bottom gets

Any of you have propspeed or barnacle barrier applied to prop or shaft?

C&C 37/40 XL, loaded for cruising, fuel & water tanks full:
Non standard engine, a Yanmar 3JH2-TBE (turbo, 47 hp)

The following assumes no head wind to speak of, and fairly calm water:

3400 RPM 7.1 kt
I run at 2200 rpms and get 6.5 knots. That’s where she is smooth but working a
little. It feels like the sweet spot. She will get 7+ if I add throttle but
vibrates more and makes more noise. Every 37+ could be a little different
depending on drive train. Universal M35 and a 2 blade max prop at 2
With a clean bottom, 7.5 @ ~2800 RPM. SOG varies. ;)

I believe the recommendation is to cruise at 80% of max rpm. For my Universal

Thanks everyone for su
Probably as many opinions on cruise speed as on best anchors, etc. Plus like
many simple questions, the answer: ‘It’s Complicated’ (also a local power boat
name!).
I faced this issue years ago when I decided to go to a 2 blade folding Gori
racing prop from my former 3 blade feathering prop. IIRC
My decades-old Westerbeke 40 is happy at 2000 RPM, maybe slightly more, which
produces a solid 6.5 knots in good weather.

I'll second Edd's response, but we have a Yanmar 3JH@E with 36 hp, and won't
get much faster at higher RPMs. Maybe 7.4 kts.
I'm hoping for a bit more when I get the bottom done (which will be happening
shortly)

Rob,
At about 2800 RPMs in my Beta 30, I’ll get the Enterprise up to Warp 7.2 (7.2
knots). If I increase the RPMs, she won’t go faster than that.
All the best,
