Thanks Dan'l!
Thanks Nordicjet..... I had forgotten about GS, thanks for the referral.
The boat already has a place diverter, so I'm good there. The boat does get on a plane, but it just doesn't do it like my old 18' jet boat did. There is a definite lag in getting this 21 up on plane, but obviously it's a bigger boat. Nothing plugging the intake suction, I think I'm just dealing with an 18 year old jet that is worn. Same logic applies to the fuel usage. I'm just comparing to our old, family 18' jet that I grew up in at the river. There is a plate behind the transom and below the jet. This Dominator I think is called an E pump, the whole thing is outside the boat hull.
On the diverter subject, the boat does tend to porpoise when the diverter is kicked up, and boat fully loaded or higher speed is not maintained. I've read other people here and other boat forums have the same issue. Supposedly a lack of HP to keep the boat "up" is the cause of this. Lowering the diverter immediately corrects the porpoising.
