90hp Mariner 2T - What size RIB??

We currently own a 16ft Sports Dory, with a Mariner 90hp two stroke long shaft, the boat is getting tired but the engines (also a backup Mariner 3.3) are spot on & have been well cared for. The boat is good for 40+ mph if anything its slightly overpowered but its great for effortless cruising at planing speeds around 15-20mph with seemingly good economy it does 30+m on 30L cruising. The boat weighs about 900kg & its a twin helm.


What size of rib would the 90hp engine be suitable for, ideally I'd like something 15-17ft as the whole lot would fit in my garage ;}

Also what RIB's come with twin helms as we quite like this set up?


I may well be up for a project/bare boat build.....

I think the searider 5.4m is rated for 90hp

I think an SR5.4 would be a damn good choice.

Totally agree - Searider 5.4! What do you mean when you say "twin helms" - do you mean a double width console (ie two people sat side by side). This isn't standard in a SR5.4 however it is possible to install a double width console and jockey seats for 4 people in. Would make a nice spring project!

I'd agree with that.

I think it depends how much money is wanting to be spent. There are boats around that size that'll easily take a side by side standup console, but they're quite wide. Ribcraft 5.3 for example-which probably won't fit through any normal garage door.

RC go in for a bit of that, dam the mould to create another, shorter model. The 545 is apparently, a shortened 585, hence being as wide as it is long.

Yeah, they only fit a transom on the 545, as a clue as to which end to put the motor.
