Ah yes obvious really So is that with a Sabb engine ?

Hi Steve Yes I'm in the same boat ( if you'll pardon the pun ) I have a copy of the manual downloaded thanks Just out of interest what size prop are you running at the moment ? And what sort of displacement do you reckon you have ? I love the sound of the Sabb on low revs and just over tick over but as it's in an open engine room it's far too noisy when its revving hard which is ok for maneuvering but not for cruising all day

I'm still a bit confused is that 700rpm engine speed or prop speed ?

Hi thanks for the advice Seems to be the same idea I've got The Sabb is at it's best at low speed they sound really strident when revving hard its rated at 30hp but at canal speeds that probably equates to 10 hp at best which is why I was thinking a bigger prop would be better

Is it not the case that I dont need to comply with the rcd if I mean to keep the boat and not put it up for sale within 5 yrs ?

Hi I'm new to this forum just wondering if anyone has any info on prop sizing I'm currently rebuilding a 48ft trad stern which is basically a bare shell the original engine was I believe a bmc 1.5 but the engine I have is a sabb 2jhr which has a hurth 2:1 box The existing prop is 18 x 12 and I'm thinking this will be undersized for the new engine given that I want a low engine speed for normal cruising Any help appreciated
