I have yet to remember to get the size of the propeller when on shore.
It was delivered by Hanse. Edited by Sea-U - 16 November 2020 at 18:13 |

I also have the 30hp yanmar sd20. It is not under powered. Flat out the boat goes 7.3kn with a tiny (too tiny?) Flexofold Racing 16x13 2Blade SD20 is max 16" in diameter but hear 17" is ok.

I use to have a Hanse 371 with the Yanmar 3ym30 and sd20. It was fitted with a flexOfold 16x10 3L, revved much to much. When order the boat I did som research and got a prop calculation from flexOfold and they suggested 17x12 or 17x13 3L and I also asked Hanse for that. But when taking delivery (back in 2004) the boat was already in the water so I could not check. after first summer I got it replaced with a 17x11 3L. Better but still revving a little bit to much. Before replacing your 30hp, buy a decent prop.

Thank you for the answer
the 370 is lighter than the 375 (800KG) can you tell me if you have a 3 or 2 blade propeller and at what rpm do you reach the speed of 7.3 |

Have not measuered the tachometer but looks like 3600. To blades. Next season I can try to measure. Normal crusing is 2100-2450 around 6 kn
