arimar not the best type of rib but i like it cos its got lots of storage areas,going to move console forwards and fit 2 jockey seats to move weight forward a bit,currently bench seat at back but bow lifts a bit until on plane

What's the boat rated to take? Quite a few Ribcraft 4.8s have had 70s installed on them, and of course the well known Avon Searider 5.4 can take a 90. I shouldn't imagine your hull is as well built as a Searider (although they look quite smart looking at the Arimar website) so I would tempted to go with something a little less than a 90 (depending on what the manufacturer says).

If the main issue is poor balance because of too much weight at the back, perhaps look at trim tabs or shifting some weight forward (or even just a bigger anchor to help trim it out).

think the max engine size is 90,already trying to move weight about but just want to go a bit faster,surely you could exceed recommended engine size a bit

If it's rated to take a 90 then get your spanners out and bolt it on! Exceed the rating at your peril; your insurance may well be invalid (and the transom might fall off!)

Of course, but not if you want your insurance to hold up should it be needed
