Hi thanks for the input.
I bought a new to me 1990 bayliner capri with a blown engine, i rebuilt it and it runs great except the boat is much slower than I expected. The tilt trim works out of the water but does not hold up for a second when in the water so I am hoping this is why I am not able to plane well. There where pontoons passing me and I was starting to question my build.

I have researched a little on trim issues and found that low fluid causes partial movement.. it moves all the way up and all the way down smoothly when there is no "load" on the motor.

So I have a few questions..
The bracket that connects the trim actuator to the motor leg does not look robust, like a piece of stainless metal bolted to one side of the motor leg and also connects to the motor where the steering "rod" goes.

Did the boat come like this and will that bracket hold up to the force of the motor in the water or was it just made to raise/lower the engine out of the water?
Will fixing the trim improve the speed at all?
and most importantly. What is suspect for the leakdown? I can usually fix things myself but its just something I have never had to mess with. At this point I have 1700 dollars all in all in the boat with a good rebuilt engine, but Id like to be able to get it planed on the water instead of plowing around the lake.

Thank you for the input.

Welcome.
Pics of the trim/tilt.
Your motor didn't come standard with T/T it was added after.
If it's the standard one and it drifts down,then the hyd.pump needs to be rebuilt.(pics)
The performance, that depends on the motor/prop combo.
If it's the original? Then the prop might be the original?If not then it's possible it's the wrong prop.
You need to put on a tach and test the rpm's.
The load will affect the performance too.

What size is the motor ? Dose your engine have tilt and trim or just tilt because tilt will only lift the engine out of the water not trim it.You can look and see if you have tilt and trim just by looking at the rams if you have one then you only have tilt if you have two one smaller fat one in the center and one longer one then you have tilt and trim.
