From the pictures you posted, I would start with two holes up, three if you could. Normal recommendations is you want to set the anti-ventilation plate up one inch above the boat bottom for every two to three inches back. The built in setback on the V21 should allow you to put the anti-ventilation plate at least an inch above the bottom of the boat. you shouldn't have to worry about any water pressure issues unless you put a jack plate on the boat and really set it high. Go ahead and set it higher than you think you need it, if its too high, you answered your question, if it runs good there, then you will always want to know what one more hole up where it needs to be.

Iffin you want it to fly raise the motor and trim it out with a light load. if your bottom is straight it should see 50 plus with that 18p. How many hours on the powerhead? Maybe it isn't broke-in yet.. It will come..

There is no break in on the E-tec motors--so stated by Evinrude.

There is no break in period like olden days where you had to go out and do 2 hours idling, then 5 hours of keeping it under 3500-4000 while varying the throttle, then varying the RPM's with short bursts to WOT for the next 3 hours. But ANY engine WILL loosen up some after it is broken in. So there is a difference between break in and broken in.

Etec starts nearly instantly, and idles as if it's warmed up nearly instantly too.
No smoke, quiet, smooth and powerful......shifts smoother too. So, I understand how / why they position this engine as an option vs 4 stroke. Can't beat the torque of 2 stroke though. |

Well then--lets say worn in--not break in as the old days.
Mine runs the same now(800hrs) as it did they first time I ranit and hammered it

Ran a little more " serious " test today - engine at same / current setting, two holes from highest.
This is with the bimini top down, approx 82 degrees, 72 degree fresh water temp (del river) This is from running with tide, then against, and recording the exact mid point speed. Engine down all the way - not trimmed out: 3,000 rpm 19.6 knots 3,500 rpm 24.3 4,000 rpm 29.1 4,500 rpm 32.9 with 1/2 trim 4,500 rpm 37.0 trimmed all the way up for max performance 5,000 rpm 37.4 trimmed out 1/2 - 3/4 5,700 rpm 42 knots trimmed out to the max speed on gps 5,800 rpm 43.5 knots running with the current and trimmed out to the max ( 50.02 mph ) Additional comments Cavitation plate - mostly under water, even with light to medium trim out at all speeds. Cav plate is out / clear of the water with engine trimmed at maximum . RPM - able to hit proper max range with full trim WOT, suggests current 18" Rebel is not too big. Fuel - between 1/4 and 1/2 full. Tomorrow - raising the motor 1 hole for sure.........and maybe 2 for the highest setting. Then re testing on the Del River at each speed to record, compare, and check cav plate position, water pressure, intake position etc....... Last edited by bgreene; 07-04-2013 at 09:03 PM. |
