Hej Tor, motorfeste-punkterne er de samme, men der skal gøres lidt plads i siderne og ende hvor rammen til dørken må justeres. Nt gearkasse -den gamle er for svag, så ms4 eller hydraulisk. Axling ok, skruen skal fornys, den skal ændres ret kraftigt. Med standard 18x18 når den ikke de omdr. den skal.. 17-18 knob opnåede vi kun på testsejladser, realistisk er det nok 15-16 i normalt trim, 14,5 har vi med feriepakning, og cruise omkring 12,5 . Det er vigtigt med ekstra udluftning også som det fremgår af videoen.

South West Florida Aerial it does yes .-)

South West Florida Aerial - yes it does, the feet line up, but you have to upgrade the water inlet as it’s too small for the more powerful engine. Also notice that the 31 is quite a bit wider than the 30 op top, and that the gearbox is bigger also.

thanks, there must be a couple of versions of that engine, as mine looks very similar to the original 30 Im picking it up tomorrow and making the swap soon, also can you tell me about the venting that you did in this video? I assume the original flange to the prop shaft can be used, ?to me it looks identical

South West Florida Aerial - yes. The old one was 18x18, and the engine was reaching 3100 rpm. The new prob. is 17x16, and should fint better, giving something lige 600 rpm extra.

We have mounted a 17x16 prob for this season giving a top-speed of 16.8 to 17.2. You are right, the old prob was too steep with 18x18.
