Bogging at low end

[Porter brewer]

My 1995 seadoo gtx has a bog and sometimes struggles to get onto plain but once it gets onto plain it has full power and sometimes doesn’t bog at all getting onto plain but I tried to ride with 2 people and it just had no power and couldn’t get onto plain I also noticed it bogs to about 10 mph when turning left but is unaffected when turning right we have tried new plugs and have good spark. Any suggestions on what it might be? Thank yall

Also the problem is gone when it is cold but after 15 seconds or so it just has the problems listed above

check compression

check compression

It’s a brand new motor less than 10 hours on it

sounds like a fuel issue did you rebuild carb with the new engine install?

What killed the first motor or did it just wear out evenly? Was the issue that killed the first motor rectified?

you should still check. at least you'll know where the engines at

Yes the oil pump on the old motor failed we now run premix to prevent this

I will I saw some where that sbt motors can still have bad compression

Yes with a rebuild kit to

someone correct me if im wrong but they machine the heads to give the engine lower compression, so they don't have as many warranty claims

We have figured out that the gas tank where the fuel pump clamps on has broken and has a recall so we are going to try to get one from seadoo

That may be true I don’t know

im sure miki will chime in on it

Yes, the SBT are known to be lower compression.

If it runs great when cold then I would be looking at fuel and electrical.
But it can't hurt to check compression also.

Oh wow, this is the first time I’ve ever heard of an oil pump failing. So it was the pump itself and not the small oil lines?

Yes it was the pump I spun it with a drill when I took it out with oil in the line from the take like how you would prime it and nothing came out and I spun it for probably 2 minutes or so

Ok that makes sense
