Anyone notice if any props porpoise less then others.I run my 25 trophy and feel it porpaoise more then id like.I do have trim tabs.Im just wonderin if a larger diamater prop or maybe a 3 blade may lessin the porpois.Ive talke to DAH and he says he can help that out as well as help it carry the boat higher.Whats your take on this.Thanks Aaron
When the water is flat mine dose it but with just a little chop its gone. Seems to do it with all props I have used and at all engine heights and trim angles. Adjustments just seem to either speed up or slow down the oscillation. If I run over 80 and air it out then its gone or slow down to about 50 or under.
I have a similar problem with porpoising with my laser 2, trophy plus and trophy props. It's my understanding that velocity hulls are designed (with the reverse chines...etc) to create lift at the stern and trim angles (and props) that create bow lift may cause opposing reaction...so adjusting engine height and trim angles works for me.
What ive been doing so far is just running the motor neutral and trims tabs down till im over 50.Im wonderin if there any fixes to this,it absolutely drives me nuts.
Hi guys, could you guys help me out and tell me what prop should I get? I know my lower is a 1:75 with no LWPU, my current prop is a 3 blades 21P exhaust through cleaver. best so far 69.7 at the rev limiter (6900). should I get 3 or 4 blades. I think it should be in the 27P to 28P ball park. Please advise.

Maybe Mickeylarge will post on this soon. I have a sportmaster and run closer to the surface than you can with your case. He has done real good with a Trophy. Let him tell you which one he thinks will work for your application.
I am no prop expert, but these boats are fairly large for what they are so I like 4 blades myself. Trophy's do work, you can get them fairly cheap, and they are a good all around prop. Definately not the fastest prop out there but if you can pick one up for 200-300 bucks how can u go wrong. Heck I went 80 on a 120 dollar trophy!!! I am looking into getting my hands on a 14.5x 28 4 blade pro e.t. I think that is the ticket for me
Thanks Mikeylarge, I already ordered a 26P 4 blades, I'm not looking for super high speed right now, I dont have LWPU, so for next season I will come back with either nosecone or a sportmaster to see what can I get out of it. So for now it's fun time. Be safe guys!! :thumbsup:

The trophy 26 is a real good prop on the Velocity. I have seen 80 with a225 etec but the rpms were too much so i opt to run a 26 raker that brings the rpms down to below 5800.
What year is the one that ran 80 ,seems the older ones may be a bit lighter.Quote:

Yup, mines an 85 but its too slow. It needs more power!!
The 85's and 86's are a lot lighter, around 1,200 lbs according to early literature. My 90 is 1,900 lbs accoring to the marketing literature. I think a lot of it is up front in the bunks and the rigid deck. The deck has very little flex with my 215 lb butt walking across it.
The 97 and newer are almost a different boat compared to the 85 and 86.Other then hull they share ver little from what I can see.The deck on my dosent flex at all.Id campare the 85,86 more to a Checkmate starflite then to a later model 22 velocity.Seems a guy needs at least 25~50hp more to run the same speeds as the older ones.I'm not sure bout the regals and how they run but they seem to look closer to the earlier ones,then the newer.This 98 of ours is solid as a rock that's for sure.
The earlier ones were lighter the on in question is a 1986 kevlar lay up. James gang has a nasty fast velocity with lots of power and I cant even touch that boat. I am sure there is alot more left if I got jack plates and set backs but I am happy with just having a family boat right now.... not racing too many people anyway. I believe they run the best with a couple of foot chop... then hold on and juice it. Maybe Evinrude will have a 300+ motor to play with someday. I would love to have one of these in the triple digits. Either way they are a fun economical boat that will still challenge most of the big boys when they least expect it. P.S. Mikey large watch out I'll run the faster prop at the Romp this time....Quote:
