Mariner 50 Range

Hi,

Just fitted a Mariner 50 2 stroke to a 4.5 rib. Does the old 1ltr per mile rule still apply ?

work on 1 gallon per hour per 10hp and you won't go far wrong.

are you saying 40hp will burn 4 gallons per hour at, say,
3/4 throttle?

I think the 1 Gal/Hr for each 10HP rule of thumb is actually at full open throttle. So a 40HP would burn 4 Gal/hr at full throttle, and considerably less than this at 3/4.

yeah-but if you work a flat rule of 1gph/10hp you aren't going to run out, which is part of the point.

i have 50 merc 2 stroke on 3 metre searider and on a 3 hour normal average run out almost always have to swap tanks i take 2 x 25 litre tanks would say i use 8 - 12 litres per hour as i say this is an average in reasonable sea driving to enjoy trip
definitley wouldnt go out with out a spare tank !!

Ditto-I've actually got 3 tanks-2x25litre and 1x30litre so if I do get one of those nice days where I want go halfway across the channel I can. I usually only take 50 litres out with me though.
