wgk36 Posted June 16, 2008 Report Share Posted June 16, 2008 Does anyone know, on average, how much more fuel consumption is increased during a breakin period? Maybe I was just spoiled with a little 9.9HP, but I find that the 40HP uses ALOT more fuel. I used to troll all day with the 9.9, and use about 2 gallons. Now, I am using the 40HP to get from spot, to spot. Once there, I use the bow mount electric motor. I used about 3 gallons in 1/2 a day and had to stop at a marina to gas up.

yellowboat Posted June 16, 2008 Report Share Posted June 16, 2008 I'm still in the break in period for my 40hp and have used 3/4 a tank in 2 weekends. Link to comment Share on other sites More sharing options...
Roy Posted June 16, 2008 Report Share Posted June 16, 2008 I have a 13 gal. internal tank on the Princecraft and the new 60HP 4 stroke and so far on 4 outings I've put in half a tank. Break-in is more expensive because of the constant change in RPM that they recommend. Link to comment Share on other sites More sharing options...
fisher Posted June 16, 2008 Report Share Posted June 16, 2008 Funny this post came up - I just got my 40 HP rebuilt and was told to go through 2 tanks of gas before it would be considered broken in. Since I troll a lot on Lake Ontario I need the motor broken in before I can do that type of fishing with it. So this weekend I went out and tried to waste as much gas as possible (to get through the 2 tanks) by criss/crossing Georgina Bay at various speeds. After about 6 hours of this - stopping occassionally, I only managed to go through 1/2 a tank (about 10 litres). I have 2 tanks on board - you should probably invest in a 2nd tank. Less time refilling/and peace of mind by knowing there is less chance of running out. Link to comment Share on other sites More sharing options...
Nemo Posted June 16, 2008 Report Share Posted June 16, 2008 It took my 4 STroke 115 Merc till 50 hours before we saw the consumption drop. It was noticeable. Link to comment Share on other sites More sharing options...
Billy Bob Posted June 16, 2008 Report Share Posted June 16, 2008 As many might know I have a 1985 50hp Johnson VRO outboard on my 16' Grumman. I am very satisfied with my mileage but of course more would always be better. I have tracked my mileage for years using my odometer on my fish finder and here is what I get. Cruising = 40-42 miles per 6 gallon can Trolling = 30 miles per 6 gallon can Since I have two 6 gallon tanks (portables) I have more than enough for any one day of fishing. Only once when I use to compete in Walleye tournaments on Lake Erie did I have to tap the other tank and even then I was on my way in only about 2 miles from the harbor.

Sinker Posted June 16, 2008 Report Share Posted June 16, 2008 I have no idea how many miles I get on a tank (portable) with my 40 2 stroke. I know I can fish all day long, and not have to worry about it though. My boat is prolly lighter though......less than 1000lbs anyways. I can go to any kawartha lake, and fish from one end to the other, and still have gas in the tank. I find its quite good on gas. I did a 32 mile run on simcoe one time, and burned just over 1/2 tank. I should really keep track, just for curiosity sake. Sinker Link to comment Share on other sites More sharing options...
