Interesting. Back in 2000, we bought a new 5.3m Destroyer from Humber. My son (the majority shareholder) wanted bags of power (young, he is). Humber provided a Mercury 90hp 4 stroke. I still have the boat. No experience on any other RIB's. It goes well, 38 and a bit knots at 5500. But it always looks down by the stern to me, but then again, Humbers have a high bow don't they. No idea of the weight of the engine - the manual doesn't say. The Merc, and boat, are 6 years old now, so probably miles out of date, but I thought the engine would be similar to your Mariner.

Incidentally, went on a trip to Iona area a week or so ago. 3500 revs. 23 knts, approx 13 ltrs per hour. Is this consumption a lot, normal, a little? - Based on newer engines. It seemed a lot to me.

Hope this all works. New to RIBnet, new to RIB's, at sea too long in big ships and sailing boats, so starting from scratch.

Mine looks down in the stern at rest too, no idea what it looks like from the outside under way though, even worse I should think always a problem if there is any amount of wind on to the stern at the mooring as it takes waves over the stern, the transom is quite low to the water but there would have to be a tsunami before it came over the bow

The 115 2/s on mine is supposed to be 150kgs according to the book, not sure what the max rated weight on a 5.8 is supposed to be but max HP is 150.

Yep. Mines so low she doesn't self drain at the mooring - well, not until the water's up to the forward end of the console. That leaves a tide mark on the white GRP, so I go aboard and pump her out after rain. She's on a swinging mooring so water over stern not a problem.

Cheers, Tony

I pump mine out after rain cos I think it would sink if I didn't

unbelievable thing - must be artificially high rainfall over it or something, the moment you see a cloud it is half full of water

Matt if you are passing this neck of the woods pop in for a beer
