NEW BAYLINER VR5 OB with some problems....

[pir6es]

Hi,

We have just received our new VR5 OB and we were very excited about. But once we started to test.... our happynes has gone. we change many times engine heigh but the result is not satisfactorium. It seems that the bracket makes the water to now flow `properly and when you put throtle down water jumps over the engine.

I atach some links to videos, so you can tell your opinion, next that we will do it s intallling tabs...

You have a non-standard engine on that boat. Here in the U.S., the engine is exclusively Mercury. How did you get an Evinrude on it?

That is a lot of transom wash coming back. The dealer or Bayliner should see these videos.

installing trim tabs wont help your problem. that motor is not hung at the right height and i bet the wrong shaft length also.

We get an evinrude for 2 reasons:

1st because the boat is on rental, and mercury service in our area is very poor. We need a fast service, and this is not provided here in Ibiza, SPAIN.

2nd In spain you can buy only the hull so you can install another engine, i know thtat there are units with yamaha. In our case we installed a Evinrude because it s weight is less and most part of our boats, and our tecnical service is provided by evinrude.

About inform the dealer, we already done, but it seems that they don t know nothing to do.... Engine is same size as the mercury, extra large, and we tryed diferents heigh, the shaft is on the perfect RPM 5600.

When I drove this boat in Nashville with a Merc 150 I did notice that there was a LOT of engine wash, and I chalked it up to the fact that the engine is not on the transom, but is instead hung off the swim platform.

In other words it may well be normal. Again, you have a non-standard engine installation, so your dealer is going to be your only help here.

Welcome to the BOC from Ibiza. You live in a beautiful part of the world.

Looks to me like the outboard is mounted way to low.

agree - plain and simple.

If I recall with an OB or even I/O the cavitation plate on the lower unit is supposed to be even with the bottom of the hull; yours is actually slightly higher so the engine may not be too low. The excessive wash may be due to the hull design with is an adaptation of an I/O hull with a mounting pad added on. Anyone here have the same boat who can post up side or rear view pics?

WE MOUNTED TRIM TABS 30CMX30CM an starts to be more normal.... but continues with a problem of hull design in my opionion. We will try to solve this problem

I have a VR 6 with the mercury 150 horse outboard. Aside from my engine being somewhat sensitive to too much trim. I am not having any of the problems you are describing. Holel shot is great Top Speed 43 miles an hour with four people and three-quarter fuel fuel .

If you were told that an Evinrude 150 G2 weighs less than a Merc 150, I think you were misinformed. I think the Ev weighs about 50 pounds more than the merc. Not sure if that is enough to cause your apparent issue (doubt it), and the built in power steering may counter some of the weight difference, but the new Evinrudes are heavy beasts.

I thought the plate was low too, but in two of the photos it looks good. If it were my boat, I would try putting about 50 to100 pounds of weight in the front of the boat. On plane, it won't matter but it might help coming down off plane. If that doesn't work, it is easy to remove the weight.

I just picked up my new VR5 150hp Mercury OB two weeks ago. Put it in the water and had a very similar thing happen when giving the engine gas. After a few hours of a Mercury technician trying to figure it out they swapped out the prop for another off a new boat on their lot and the difference was immediate and reached 5100rpm fully trimmed down. The factory prop was an aluminum 4 blade (Spitfire 13x17) and they tested a stainless steel three blade (14.2x18). They assume the aluminum prop was flexing but mine looked just like the OP's videos like it was trying to dig a hole straight down with no forward momentum at all.

Have other issues with the engine not being able to trim up enough to get the prop out of the water (they are working on that now).

Good luck with yours. Love the boat just hate to have it in the shop a week after I bought it. First time boat owner so not the start I was hoping for.
