2019 E-Tec HO 225 HP Max RPM range

Merry Christmas to all.

Finally felt comfortable running the new motor (15-20 hrs) at WOT for a shor time and the digital tach danced back & forth between 4850 and 4900 RPM.

 

I think this is a little below where it should be--correct?

 

Suspect slightly over-propped...Correct?

 

Thanks

and Merry Christmas again

What is your engine's model number as all makes of outboards do not go by years anymore, only by model #.

 

For any of the 225 HP engines, your top rpm is way too low. Are you trimmed out for best speed at that rpm?

 

For most of the motors it is best to be in the 5500-6000 at full throttle and trimmed out.

 

What type and size boat, what model and size prop, and how fast does the boat go?

When we get your answers to these questions, we can then give a more informed recommendation to you.

Motor is en ETec G2 225 HpP

Model # H225HLAHA

Serial # 5533811

 

I let the suto trim work and it seems to be at least very close to where I would trim it but I did not use the trim.

 

It is a 24' ElPescador Classic   http://www.elpescadorboats.com/classic.html

I have an RX4 15x20 prop

 

It is a tunnel hull and isn't designed to be a fast boat--top speed now is 42mph +/-    was watching the RPM more than the speed.

Took photo of prop and stern, transom of boat but get error when trying to load.

Re: 2019 E-Tec HO 225 HP Max RPM range

An 18" pitch RX4 may bet your engine rpm up into the recommended range of 5400-6000. It is optimal to be at 5600-5800 rpm.

The Evinrude G2 E-TEC often can be mounted higher on the transom than with other motors due to its setback, low water pickups, and gearcase design. It may be to your advantage to experiment with engine height, one hole at a time, to look for improvement in both rpm and top speed.  It is trial and error to find the sweet spot in performance and economy, but your time will be rewarded in fuel savings and enjoying the "wow" factor.
