How Many have Tenders that Consume more Fuel than the Mother Ship?

It's funny, our 43ft boat churns along at 5-6kn drinking 2-3 litres of diesel per hour, my new tohatsu 9.9 s stroke for the tender consumes considerably more... Just wrong!

So how many of you are guilty of having tenders that consume far more fuel than the mother ship?

Re: How many have tenders that consume more fuel than the mother ship?

It's kinda hard to compare a slow speed diesel, to a high speed gas engine !! but there all that way !! Ive never had an outboard, 4 stroke or 2 stroke, that got any type of fuel mileage! I don't think anyone really has ! But it's so darn hard to get the big boat up to the beach !!!

I second slow down, Midrange RPM is much better for fuel consumption.

my dink uses oars or sail. I don't have a motor for it.

That's almost exactly what my Tohatsu 9.8 4S uses at WOT, I cruise at 5kt at just over 1/2 throttle and use 1/2 gal/hr. Is yours a 2S?

At cruising speeds our 4 stroke outboards (Honda 20s) use about 2 litres/hour.

The 18 hp 2 stroke dinghy motor is a different story however.

Reading that again I see it says "s Stroke"...I'm betting that means 2 Stroke and yeah...they suck it up. 50% more according to Tohatsu. In this case it's not lighter either...so what made you choose the 2Stroke?

Yes, we do.
We have a Tohatsu 6HP 4 stroke on a 9’ 2” rib dingy with a 3.1 gallon gas tank. If we use it at half throttle or less it will last us 6 months.

Slowing down is the key to saving fuel in a dingy

Re: How Many have Tenders that Consume more Fuel than the Mother Ship?

Astrid, our dink has oars and sails but we do have a little outboard that we have used a time or two! Mostly we row, unless we are gonna be in an anchorage for 3 or 4 days then it's worth setting up the sails and such !

Me too. The old 2 stokes are bombs and always work. I have had a 1988 model to this day and never been in shop or any issue what so ever. Just run good clean fresh water thru it, change plugs every 2 -3 years, and run dry before storage.
