Max engine size / weight?

[treerat]

All

When I bought the boat (a 4.5 Rimini - that measures 4.3!) a couple of years ago she arrived with a manual tilt 40 hp mariner.

She seemed very nose light until I added an anchor, chain and rope into a bow box (none was on board) and now she balances nicely. However I'm thinking of going up an engine size as with 2 or 3 divers on board she struggles - runs fine with just me, wife and kids.

There is no plate on board anywhere that I can find that should give the maximum engine size or weight - is there a rule of thumb that can be followed or is it a case of find an engine that isn't too much heavier and see? I was thinking of moving up to a 50 as I've been told a 60 is twice the weight?

Rather than swap engines, try swapping to a smaller pitched prop when you're going to load up (cheaper).

AFAIK to comply with the CE directives, the boat should be plated.
