1900 proV bow lift

[Alby]

I am currently running a 19" three blade prop on a 150 saltwater
yamaha on my 1900 proV SE. While the setup works great I would
like more bow lift if possible. The max horsepower for the boat
is 200 HP. It may be that I can't get the extra lift with my
present power. Thought you fellows might have some suggestions.
The wife tells me that buying a new motor is not an option.

Go with a 4 blade prop

Get ahold of your Yammy dealer and he can get you in touch with Hydro-Tech.
They have bolt on Horsepower available...cheaper than new engine.

ALBY, I HAVE A 1900 PRO V LE WITH A 200 YAMAHA AND A JACK PLATE . I DONT KNOW WHAT YOU MEAN WHEN YOU SAY BOW LIFT? MINE PLANES DOWN JUST GREAT. AND WE CAN GO 54-56 IF CONDITION ARE JUST RIGHT,AND THE PLATE IS SET PERFECT. AND THAT IS TOO ##### FAST AND MY WIFE WILL TELL YOU THAT (SHE HATES WHEN WE GO FAST)SHE IS NO FUN ANYMORE.3 BLADE PROP.WHAT DO YOU MEAN WHEN YOU SAY BOW LIFT. NICE BOAT WATER ROCKET

From what I have gathered lately about prop trends, you should make sure you are running a prop with a high "rake". This is the angle beyond 90 of the tailing blade edge when compared to the angle of the hub. It is this drawn back property of the blade that gives a high rake prop more bow lift. 3 blades with these characteristics are the rapture, stiletto, and turbo among many others I'm sure. I experimented with many of these and they do make a difference compared to a prop with less rake. The other thing to be aware of is the cup of the blades, or how much they are dished out. This gives a prop a stronger bite on the water and allows you to trim out farther than a non-cupped prop. The 4 blades I have heard are very good at lifting the stern, which when you think about it probably simultaneously helps the bow lift because the boat is overall a bit further out of the water. The big sell on 4 and 5 blades is that they remain locked up with the water in rougher water than the 3's, but typically at the expense of some topend speed.

It would be helpful if you give us more details on the actual prop you are running now, and at what rpms at WOT, engine height, ability to trim up without cavitation, and so on. Then you could get some more specific advice comparing to how others are running. Sounds like a nice rig that just needs a bit of tweaking.

Alby, Just try a 4 blade or a High 5. You will get much better Bow Lift.

I run the 1900SE with a 200hp Maniner had the same problem,went to a 21 inch high five.Works great and did not loose no top end speed. I bought mine from Kenyon power sports out of Florida,it was the cheapest that I found.

In 1996 Lund made a 1890 LE which was replaced in 1997 with the 1900 LE and SE models. I had 1890 LE with a 150 hp Saltwater motor with a 25in shaft. It came with a 21p prop and ran about 50 to 52 mph @5000 rpm with almost nothing in the boat and 1 person. I then ran a 19p prop with the boat loaded with fuel,batteries,livewell,ect because the 21p was too steep. The rpms were now with that 19p @ 5100 rpm at my speed was about 47mph. I then went to a 17p and my rpm was @ 5400 and about the same speed and my fuel economy was much better and the boat jumped out of the water. I then raised the motor up on the transom and that is when I noticed the nose of the boat would not come up. I put it back down and it came back up. I felt the that having the motor deeper in the water pushed the back down and the nose up. The 3 blade props I ran did not seem to make a difference in getting the nose up. Lets face it the nose of that boat is heavy with the batteries and livewell. I would check your motor height and I also see from the other posts, people have had luck with 4 and 5 blade props.
