New Suzuki.

[danny]

Does anybody have any expereance with de big Suzuki's
We are about to buy a new engine and Suz have great prices and also comes complete with prop and helmunit.
We would like to go for the 250 although the boat should be able to have a max of 225 hp.
All three engines (200,225,250) have the same weight.
I had the plan to make some changes on the transom, now i could reinforce it with some polyester and stainless steel.

Great engines, i have installed 3 X 250, 1 X 225 and twin setup 225p Suz.
3 of the engines has around 500-600 hours without any probs except a that a rock was in the way under the water
The twin setup has only 20 hours and one engine has around 50 hours.
So far so good.

Maybe you know this also.
The current engine is a long one and the transom should have a ultralong one.
Eventhough the boat is going fanatastic.
The cavitationplate is 12 centimeters higher than the bottom of the boat.

I always thought that it should be at the same height. Is this true ?

Transom height is 60 centimeters.

Last weekend there was a apeedboatrace nearby and I noticed that all of them engines where also mounted higher. I really don't think that this Osprey is meant to be a racer.

What to do: buy a long or ultra long one.

Dan,

Make sure you have the correct shaft length according to the engine manufacturers specifications. We wrecked a Honda BF225 in less than 120 hours - caused by water ingress into the cylinders. The general consensus was that this was caused by having a short shaft instead of a long one.

Regards.

Hi Danny;

You shouldnt have Ultra long, the 7m should have a extra long shaft or long shaft depending on how they cutted the transom.
I always install the engines a little bit higher and trying to find a good prop for this, offcourse it depends a little bit of how you use the boat.
12 cm sound maybe little high but it depends a little of the prop.

Yes and no, depending on engine, boat, prop etc etc.

and a ultra long one.

I didn't know ther was a extralong one in between !

How much higher would you reccomend the prop then?

I can't find a extra long on the suzukisite.

Ian, Help me a bit. My english isn't that great.

What do you mean by: caused by water ingress. Did water get into the cilinder through the exhaust ?

Dan.

[Petrov]

63,5cm is the extra long at the most manufacturer, i can se that suzuki has extra long as Ultra long.

Sorry Dan!

Water got in to the cylinders. We don't know how, but think it was through the exhaust. The engine was mounted too low to the water line.

Hope this helps.
