the boat i have in mind is an excaliber 6.5m,heres a better idea of the boat.like all men i need an engine thats not over the top on money,that will at least hit near the 40 knot mark and, of course reliable. (note this is not my boat).

I dont think anyone appreciates how hard it is to get one of these big, cummins, yanmars etc into a 6.5m rib.

The thing to do is ask the manufacturer what engines he will fit, it might be that he wont touch some types of engine, and could tell you for sure what engines wil actually fit in the boat.

However if you are short on space theres a Yanmar 4LHA 240Hp or next year a VW v6 225 Hp which is even smaller still.
You are nuts.

succinct as ever WJ!

You would have awful steering problems with that much diesel power in a small rib

Advice from boat manufacturers is a good atart. Mercruisrs seem to be good lumps 120/170 HP Steyr are good engines but a bit too techy and therefore reckoned to be iffy however well worth a look and cost effective last time I looked. The you always have the yamaha 370 165 HP lump.


If you have to have a bigger engine and have got a shoehorn then go for these babies

Not to mention they weigh well over ton. They'll just about sink the rear of a 6.5.

Hmm, nice lookin boat with some nasty handling tricks from a 240 Yam glad it wasn't my 30k

Richie, for my money the Merc 120 TD or the Yam 165 TD, both been around now for a while and used in lots of ribs.
