Hi
I have a 3.8 meter zebec SIB with mercury 15 hp short shaft, and i a few questions that may be related one to the other:
1- i have a 4 part wood floor. where should the side rails be fixed? starting from the rear touching the transom or as i was told from half the second to the third( the one touching the transom being the first)?
2-used to have 6 hp outboard but no plaining and no fast speed. now with the 15 hp with two persons onboard i reach 30km/h but sometimes after plaining starts the outboard seems to such air and make false high rpm with no much response of the boat. It may be happening if the boat if not inflated to the maximum or in choppy sea but i just cannot connect it to certain reason. could it be possible that a SIB needs a long shaft?!! boat not fully inflated? side rails in the wrong place? ftubes get farther of each other during time and floor not tight enough?
3-what is the best way to get on plain?the one in front should be at the bow until boat plains then comes back to the bench? should i change something with gas at some stage? is it natural that inflatables loose plaining in choppy sea very often?
alot of questions alot of thoughts..
would be happy to provide any information needed.
would appreciate your help
