Would maintenance and service costs be considerably more for twin 90's against one 200?

Hi

Twin 115 (normally same block as 90hp) would really be comparable to a 200hp.

My 90 four stroke on average used no more than a litre per mile, my 150 optimax also used no more than 1 litre per mile (+ oil costs). All average and cruising speeds

Things to consider-

-you can use up to double the amount of fuel when in rough seas!

-Cost of counterrotation!

-Transom Weight!

In my opinion get a Susuki 200hp v6 four stroke and 15hp aux, you will be under a litre a mile at cruising speeds. You will also save yourself about 5k.

In my opinion these days, the only reason you would go for twins is if you need more hp than 1 engine can produce.

This is why i'm going for twin 250's

Yep, about double in fact as the biggest cost to servicing is labour, so thats two lots of water pumps to be inspected, two lots of oil and filter changes etc.

only one engine!

Maybe I've just been lucky, but I've never had a mechanical breakdown. My philosophy has been: make sure engines are well serviced, do your pre-start checks everytime and keep your fingers crossed. My new rib is going to have a single Suz 250. I haven't even thought about an auxiliary.

Does anyone have experiences of an auxiliary saving their bacon. Am I stupid going to sea with one engine and only a paddle as back up?

depends where your going I suppose. I wont be alone more than 10nm out so a 250hp and a VHF should do the job. Any further and I'll be in company of other ribs.
No aux. on mine, not yet anyway.
