Fuel "economy" of Quicksilver 380

smpayne321 · 03 July 2008, 19:46

Hi to all,

First post so please be gentle.

I'm keen to get into boats and think a RIB/SIB is the way to go. RIB's seem a bit expensive so I'm swaying towards a Quicksilver 380 with 25hp Mariner.

What sort of "economy" could I reasonably expect to see? I appreciate it would depend on the weight you were carrying and whether you were flat out all the time, but for arguments sake, say 2 up and gentle cruising.

A browse through the forums suggests 1 litre/mile but that seems to be for bigger RIBs.

Thanks in anticipation

Stuart, I have a 3.9m solid hulled (and tubed) boat with 20HP 2stroke. So should be in the same "ball park".

I can get 2.5-3 nm/L

It also takes me twice as long as a typical "big boat" to get somewhere so on the plus side that means that in a day I travel half the distance and so use even less fuel. A full day for me is typically 25L of fuel.

My 25 yam which i think is the same as the mariner did about 3 miles to a litre pushing a 4.2 futura I would expect it to be better with the 3.8

Hi there , I had a 430hd quicksilver with a 25hp 2 stroke mercury did 21 knots flat out and approx 2nm per litre flat out ,a bit less if running at 3/4 throttle.

as a comparison I had a 20 honda 4 stroke on a 3.8 air floor that did about 6miles per litre same wieght engine as a 25 Yam / mariner

Much appreciated.

Thats considerably better than I'd thought/hoped.

You fuel economy or non economy will depend on how heavy your hand is, that is the throttle at wich you sib. 1/2 to 3/4 throttle will be best suitable for nice economy & performance, but will depend on the number of passengers, cargo on board.

Happy Sibbing
