My F-rib 330

SO today was the first outing in the Frib. Wanted a nice easy place to get familiar with the outfit and launching etc so just went up a local river for a 3 hr round trip.

Great fun had by all, even though mostly at displacement speeds as the river has a speed limit, but was a good shakedown.

Did the obligatory "forget to raise wheels" error and lost a bolt trying to swap them in the water as I realised I had put them on the wrong way round

Did creep it up onto plane once or twice and fiddled with trim settings etc. It runs soooooo muuch better when on the plane - now need to get out in the sea to really try it out

Cheers,

MM

It's good to get that first outing but as you hint the river is a little frustrating and the sea is needed to really find how the outfit will go.

I'm happy to trickle along some places when the mood takes but lifting onto the plane just feels so much better... particularly for you as you have a very skimmy hull shape that will go so well for a 15hp.

In my small onboard spares kit I always carry spare bolts/pins for transom wheels as they are so easily dropped.

Good shout that I used a screwdriver from the tool kit to mount it temporarily when getting the Frib outta the water but it would make sense to have a spare bolt or two

Cheers,

If you can (not sure on your bolts system) use pins tied together with Paracord - only ever loosen one at a time.

bolt wise use drop nose bolts no spanners needed

Thanks, useful info

The trip was really good fun and we probably will do the river stuff a few more times as the sea around here doesn't have a lot to explore so that will be more for fishing trips etc.

With the river there is quite a long navigable reach so we can do day trips/picnics/take the dog etc.

We can only go at displacement speeds on the river (8kn max) so I am seriously thinking of picking up a little 5HP 4 stroke for river use. Would be much easier to carry/mount and a lot quieter when poodling along than the 15HP 2 smoke.

Fuel economy (from a ease of use, not cost point of view) was a consideration as well, I used about half a tank (10l) for a 3 hr cruise, but I think that was cause most of it I was in "no mans land" between displacement and planing, at 4kn the engine was on tickover, at 10kn it suddenly picked up on the plane and flew at quite low revs, in between it was working hard to go nowhere

I even wondered about going down to a 2.5HP, but from what I can see these only have onboard fuel tanks and don't have forward/reverse. (I quite like the Mariners twist grip style Fwd/rev setup)

Any thoughts on suitability of smaller engine for river work at displacement speeds on the Frib?

Cheers,

MM

For many years my river engine has been a 1980s Mariner 4hp as in the pic below.... it was preferable on the river to the 15hp 2-strokes we ran for years when at sea. But now I have the 10hp I think I'll just use that.

Anything 4-stroke 4-6hp would suit you and it would just be down to brand preference, the deal offered and features you wanted.

Cool, that backs up my thinking. I think the only features I am interested in is remote fuel for longer trips then it is just about having reverse gear. I have seen some smaller engines that do 360 pivot but that looks like a lot of hassle compared to a gear level

Cheers,

Paul.

2.5's are usually air cooled buzzy noisy little buggers.

You say that - but my 2.5hp Suzi 4T is water cooled with a through leg exhaust and N/F gear. Weighs 13kg - great car boot engine but unlikely to be man enough for the OPs application.
