I have a 25 HP 4 stroke Honda on a 16 ft Lund. Best running motor I have ever had.

But

It is slow to get to speed and not as fast as family w 25 HP Mercury and Eveinrude.

what might my problem be or is this just Honda

thanks

BRP continues to own the E-Tec technology and maintains the rights to it. Mercury did sign an agreement with BRP to provide outboard motors for the boat companies BRP owns.

Mercury bought them out so who knows what will happen!   CARPIO

Vegas’s comments are why I’m bummed to see the Etecs go away...

They ran 100 to 1, used less gas than most four strokes, had a great hole shot, same emissions as a four stroke, and just as quiet too. They also weighed quite a bit less as compared to a 4-stroke. 

I was really hoping they would sell their design to one of the other outboard manufacturers...

My buddy had a 40 Honda and it was a dog. I always thought the prop looked small.

I repowered to a 50 HP tiller Yamaha on a 17 foot Tuffy.  Man I loved that motor.  But, being a four stroke it was noticeably slower to get on plane than the 30 HP Mariner that was on that old boat.  Maybe even a click slower on top end speed.  I made no prop adjustments to that rig.   

I think in general those four strokes won't get the speed of a two stroke engine.  But I'm no mechanic.  And given the overall performance of a 4 stroke versus 2 stroke, I'd give up the power and top end speed for the better, smoother, quieter motor.

Hondas known for two things. They're generally not the fastest. But, they are just about indestructible. 


Most Lunds are fairly heavy boats so a 25 might not be enough power to begin with, no matter what brand. What does the plate on your boat say? Generally you want to go with max power for any given hull.

Could be the motor is a little under powered for a 16 ft boat. The boat is probably rated for a 40 or 50 hp.

Can't speak for the other brands but having a Evinrude E-Tec I can say that these are significantly lighter weight motors due to being 2 stroke engines.  The 2 stroke technology also provides a power stroke every time the crank turns whereas the others are 4 stroke power every other turn. Thus you will see the 2 stroke tech beat the 4 strokes probably every time.

Agreed.  If motor is running fine, not missing coughing etc, look at your prop, also look to see how deep the cavitation plate is. It should be at the water line when on plane.
