All (most) CR gearboxes are the same Steve, next time it goes pop buy a right hander. Speak to some experts but I think you'll find the boat will drive just fine with 2x RH boxes

There's a Quinquiri passenger rib with twin etecs over here that went thru several LH boxes before sticking a RH on and never looked back.

If it were something we were doing, surely the other gearbox would suffer too ....

I wish Barrus would sort out their counter-rotating Verado units
Hmmm, I did wonder yesterday ...., but put it down to not being used to the boat sound. I'm amazed Ricks not picked it up already....

Can you switch to the new bigger HD cases. (might have done already) They seem to be fairly bullet proof but an expensive move. Maybe Barrus would consider helping you out. I heard on VOG that Merc are doing some good deals to swap the older ones out but you can't always take that sort of thing in face value.

Hope you get sorted quickly.

Second Martini's comment regarding 2 x RH rotation. I had a much smaller scale boat - 6m chinook with twin 40's both RH rotation, never any problem at all, handled fine.

Cuts down on cost and amount of different spares needed to be carried on station or at divisional base making engine swapping /interchangeable simpler ,, also saves having to keep another set of spare props on the boat ( left & right handers).or confusion perhaps with a prop change at sea in difficult conditions .

Seems a pretty fair question. I can see where he's going with it

I do a lot of work for one of the RIB charter companies on the Thames. They operate 5 RIBs all with twin engines (mainly 200 HO etecs). Gearboxes going is a monthly occurrence (latest one was this week); there's so much rubbish in the river, all it takes is running into a tree or pallet that you didn't see (quite hard in the murky water on a choppy day). That combined with an average of probably about 6 hours a day running means you are putting a lot more wear on the boxes than a normal leisure user would.

Might be worth doing a weekly check on the condition of the oil which would highlight any problems early on.

PS. I know of another charter operator in the Solent who had a box go on his 6 month old 300 Verado last year.

PPS. They have now changed to running just standard gearboxes (no counter rotating models) to make life easier; only have to have one type of spare. It makes very little difference to performance.
