Inboard Petrol Rib

[Zippy]

So what are the thoughts on one??

Given legally its pushing it declaring 60 / 40 split on diesel for a rib, and the price difference between fuels isnt that significant anymore.....

What are peoples thoughts on an rib with Mercruiser 6.2 MPI ?

[ShinyShoe]

How you planning to heat it with petrol? Or am I missing the point?

If you're going petrol, go outboard. The inboard bit is one of the downsides of diesel. What draws you the the Mercruiser?

^ What he said, plus all the crap with bilge blowers etc on petrol inboards.

We had a 8.6m with inboard 5.7 mercruiser. Wife loved the sunbathing platform. Was a great boat,fuel was acceptable. Now running a twin diesel with D3 160,s. Same performance, better economy and range. Get commercial rates on fuel so £0.73p a litre. And a cabin. It's all relative to what your boating needs are.

I think there was a reasonable case to be made when outboards were all old school 2-strokes as an inboard was the only way to get a more fuel-efficient 4-stroke.

Can't see any merit in it these days.

Have to agree John,although a V8 sounds good.

If going for an inboard, I'd say diesel due to availability of fuel and the fire risks with petrol. Outboards have come a long way and I can't see any real advantages with an inboard petrol engine.

Sorry, I wasn't clear. It's difficult to legally justify the 60/40 split on an inboard diesel rib so therefore fuel cost for petrol and diesel are similar.

On preference, outboard would win but options are limited and this is not a new build. Ilmor petrol would be nice mind!!

Yup. Done d3's with a cabin and beds and d6 with a speed machine but looking for simple day boating again.

No doubt there are fire risks but there are also thousands of petrol boats around so they can't all blow up!

New petrol engines hp for hp are cheaper than diesel and the extra cost justifies a lot of fuel!

V8 petrol is gonna have a lovely sound!!

Preference would be 350 verado but beggars can't be choosers

resale will be better on a diesel - people don't expect petrol inboard RIBs, whilst you may be feeling too honest to the tax man to try the 'heating' line others wont, and anyone considering coding it will be unable to with a petrol inboard.
