Fuel consumption

Re: Fuel consumption

I don't have deep pockets and my 888 combo is 34-years old. I do run her 2500 to 3200 rpm but that is the max. Just because the max rpm is there does not mean you need to run it that high --- old marine mechanics just want you to blow her up so they can make some money

I can get on plane and stay there backed all the way down to 2000 rpm. A marine engine is under constant load at any speed and 2500 rpm is a comfortable speed for me and works the engine plenty hard to raise the heat and keep moisture out of the oil etc.

Newer fuels without lead or additives and newer synthetic oils keep an engine very clean inside compared to days past.

Think about your vehicle --- compared to your boat it would be like climbing a hill no matter what direction you travel --- so much of an incline that at wide open throttle the engine will not increase in rpm much past the point where the engine makes the most power. If your engine makes 300 horsepower at 4400 rpm and you are running wide open throttle at 4500 rpm than you are using all 300 horsepower and placing a huge load on the engine. This is why there are so many cooling issues etc.

This is why a marine engine does not last near as long as an automotive engine. The marine engine is running under a heavy load at all times --- your car going down the freeway with the A/C on is making on average less than 15-horsepower.
