Hi - Newbie Alert :-)

Hi All,

I’m new to this forum, not totally new to boats, but there’s lots to learn about ribs for sure. Previously had a SIB and a Quicksilver Commander 600 with a 115 Mercury.

We have recently bought a Humber 5.5M RIB, not sure of the model or age (we think old!) My partner bought it off EBay. The engine was no good (old Johnson 70 2 Stroke) so we’ve just upgraded the engine to a 2006 Yamaha 115 4 Stroke and had it all professionally fitted and set up.

Now worried that the engine is too big for the boat, as we took it for a first test (River Trent) and when we opened it up a fraction, we did get water over the transom. Hopefully, this is more due to trim and speed v engine too big ��

We’re going down to Cornwall next week, so we’ll see then what happens.

Thanks for reading ��

Hi Beerbelly, thanks for your reply. I’ve attached a pic.

That’s not a Destroyer.

Thanks, any thoughts on what model?

I'm going to suggest an Attque (or or it;s modern counterpart) I've got the O-pro's Grandad (max 60 HP!) , and it may just be the angle of the pic, but it looks quite a flat-ish V. can you get a pic from below, or better still - the transom?

WRT water over the transom, I assume you were fully trilmmed in when you opened up?
