mounting engine to 4m sr

mrs bought me a nice secondhand 55hp yam engine for xmas
but do you mount it exactly dead centre of transum or slightly to one side? never fitted one so this is my first time and dont want to mess it up as mates say that if i get it wrong she`ll pitch all over the place

any help be excellent

hi, on the SR4's i have had in the past , always mounted on the centre line and had no problem, you do realise that the max HP on a SR4 is 50 hp.

I had a Yam 55 on mine and it went fine, just inform your insurance to make sure they're happy?
Had mine in the centre.

I assume by sock you mean a drain trunk? if so, no......

.....unless you are ftting twins, in which case the drain sock needs to be centre on the transom to fit between the engines!

as Chewy said, MAKE SURE the insurance company are happy, as fitting it and not telling them could leave you wide open to all sorts of problems if god forbid you hit something / injured some one, better to be safe than sorry.

I am not sure, but I believe that the old Yammies are not measured at the prop. So there is a 10% loss in HP... so you still have a 50 Hp
