Hello. I have a 50hp Mercury, serial number OT571575 that I recently purchased. Seems to idle good, runs pretty good on the river but at WOT it's only going at 4000 rpms. The other day after being in...

Thanks for the opinions. Looks like I will be going with a Vance 6 inch. I am unsure on the performance plate? If it has any major benefits

Do you use the performance plate on it? I see they offer a plate for it and just wondering if its worth it.

What about Vance jackplates? I have heard a few people run them.

That doesnt look good. From the picture it looks to be cheap metal

Will a jackplate help with control?
What brand jackplate?
And thank a lot

Any particular brand I should go for or stay away from?

Thanks swamprat. I tried it this morning and it does run better. I am running about 56 to 57 by gps.

I have tried a raker prop and it works a lot better than the renegade. My RPMs are up more now and so is speed. I keep hearing people say I need a jackplate. Which jackplate would work with this...

I just got a new raker prop. Haven't tried it yet though. Does anyone know what jackplate would be best to use?

Have you tried pushing the key in when trying to get on plane?

So I may need to change the prop

I have checked with the local shops and no one has a prop to try.

I did change the high speed jets over. Before changing them over I soaked the carbs in chem dip as well before hand.

Seems like everyone thinks it is the prop. I just hate to but one and that isn't the problem.

Plus side is that my tach works properly.

Would like to try a raker before I purchase one

Ok thanks for the advice. I will try that next and see what happens. I am in the process of changing the tach to another one just to verify that it is work properly

I have a recently new to me Hydrasports 185E with a 175 Johnson faststrike. Over the boat is great. Idles good on the water, planes out fine and overall runs great. The problem is I am only getting...

Thanks for the info, it is a Renegade prop. 175738 number on the prop.

I had someone come look at it with me today and they don't believe anything is wrong with the motor. They said in their opinion, I should change the prop. Said a 25 pitch 4 blade might be to much

...

Ok I will check that

I am not the original owner. I purchased the boat a year and a half ago. Every since I purchased it, it has stayed out of the rain under a big shelter or in a building.

When I purchased it, it...

Something is definitely wrong with mine then

I checked the height of the motor and it is 2 1/2 inches below the pad. I also checked spark and ever cylinder has spark. I rechecked compression and 4 cylinders are 110 and 2 at 108.

To me, the...

I will check everything that has been suggested today and let everyone know the results.

I will recheck something on the motor. Not really sure what to check. I don't have much weight on the boat. Timing is good. The vro pump is new, fuel lines new, stator new, power pack new, rectifier...

So I rechecked the height of the motor and it's 4 inches above the pad.
