Hey Brian and Ray

How much do you want for one of these?

I,m asking $ 1500 plus shipping cost have everything plus manual. Stern Jack was us ed for about 35 hours in perfect condition.

Hey Brian

What did you have them on, and what kind of results? Did you have to change props? Did it clear the swim platform, or is there a way to limit travel so it doesn't hit?

I it on a 1989 Checkmate 25 Convinser .Its hard to say what gains came from the stern jack I repowered from 330hp to 450hp at the same time but I did gain about 15 mph.Had no clearence problems.

15 MPH sure seems like a lot from 120 HP upgrade. I would have to think the combo of the two "woke up" the boat.

I am getting ready to drop in a new motor and I have a Stern Jack sitting in the box.

I am going to do a GPS run with the stock 7.4 MPI, then do the same run with the new motor (about 200HP more), then put on the Stern Jack so I can see what the results are for each.

Should be interesting...I will post when I get it all done.

there is a complete land and seas bravo extension on ebay. It is at $700 and no bids yet.

I installed one on a 26 POwerQuest and saw no speed increase at all!! Ialso tried several differant props but no help. I guess it depends on the hull design.

I go away for a few days and I have 16 post. Thanks everyone for the help. Currently I am just contemplating on the Idea. I am still waiting for the motor to be installed in the boat, I would like to do the land & sea in the next few months, after the motor is broken in or over the winter. I remember seeing a add. in some magazine where land & sea posted there results on specific hulls. it varied considerably. from 2 - 10 mph depending on the hull. I believe mine would be a good candidate for 3 - 4 mph. but who knows

Thanks for all the help

On there website they show actual boat tests. demonstrating before and after installation speeds:

Thanks Ray. There is a 28' wellcraft at the bottom. I assume it is the same boat as mine and it got a 5 mph speed increase. This is something I will defiantly be getting in the future.
