So comparing our 10yr old 75 horse 2\ giving a little over half a mile per litre to a nearly new 4\ giving back under a mile per litre = it aint so bad!
Saying that, if we get out as often as we plan a 4 stroke would pay for itself quickly.
Once we've had some more miles out of her we'll have a better average on its economy.

Yep, totally agree with Sharkey. My first trip of the year at the weekend, lost some that experience you normally have by going week on week. Hit plenty of slop at 19/20 knots, started to ease back, no improvement so went the other way up to 24 knots jumping/skimming the top of it and way way better. Also better economy cos there is air under the boat. Keep the boat totally level to, don't accept the slightest tilt. Move one bag if that is what it takes.
Norrmal economy just under a mile per litre with a 90hp 4 stroke. Would love a 135hp Honda or a 150 if I was brave.
What year is your boat too Pete?

I think both boat and engine is 97'? Dan and Ad may confirm.

pete we use to run a hardy with a 60hp merc 2 stroke keept it at keyhaven and we would fish christchurch leadge,or out of the back of the island. we use to take 4 x25ltr tanks with us and always used at least 3 of them. we then fitted a marina 60hp 4stroke big foot to the boat (which the salesman at the london boat show said would be no good at all for our boat,slower pull up and less top speed.) well how wrong he was.what a transformation ! the best thing we ever done. and it was unreal on juice. our normal trips were being done on just over 1---1 1/2tanks hard to beleive but the truth.we also run a 100hp yam 4 stroke on another boat fantastic motor as well....get yourself a 4stroke and youll never go back!!!

Yep, no doubt we will sometime in the future. The engine's running well (touch-wood) but still gaining our confidence at the moment so we wont be offshore wrecking as yet but I do like the idea of a shiny new 4 stroke. Thanks for the info  |

Weve got a 140hp mercruiser inboard (obviously 4 stroke), sitting at 18knots (she will do 30 ;D) we done 35NM last friday and used 50-60 quid of juice. Im not fussed about paying that really as its not everyday you have to pay it unlike a car. My mates got a 100hp Yamaha on exactly the same boat, does just about the same speed and just about the same fuel  We have only just anti fouled her for the first time and the difference it makes on speed and fuel consumption is unreal. Just before she came out the water, with a dirty bottom she was doing 15knots at 3500rpm and did 30quid of fuel to 12nm  Now she does 18-19knots at 3500rpm and the fuel economy as above |

I think both boat and engine is 97'? Dan and Ad may confirm. Yeah, I can't remember 100% either. It's in that ball park give or take a year. It has the wider, square sided ribs (4 of I think), not the skinny ones and not the new style. A quick look around the boat compound confirmed there are loads of variations! |

Thats good, you've got the better model. The earlier ones were heavier, so slightly more juicy to run but a better ride as they don't bounce so much.

If the boat is the same age as our Koden sounder it was made in 1904!!!
1997 sounds about right to me.

With a few more trips under our belt we got a better average for our economy -
We're getting about 19 miles to a 26 litre tank, so not to bad considering theres always 3 onboard. Better than the 36 litres for 18 miles we first thought.
