MY 09 OPTI will not go over 4300 RPM. It has a full dress 2013 power head.
I ran it a month ago and it ran fine. I took off from the boat ramp and it was running ok.

SilverFox579 - Thanks, will do
lpugh - Thanks for the schematic, I will check the voltage on the Y/R solenoid wire the next time it does it.
Yesterday I was set up to test and it worked the way...

Thanks for the reply Don,
I did not hear any click, but next time I will take the engine cover off so if the solenoid is clicking, I will be able to hear it better.
I did not touch the controller. ...

Hey Don,
I know it has been 4 months, but I am doing maintance on the Opti and wanted to ask you about the solenoid. I have check the Engine Harness Connection, and the Yellow W/Red Stripe wire...

Don, I got my Ohm meter out and found the solenoid had some resistance from where the red top power supply cable bolts to the solenoid and the yellow one. Is this normal?

Thanks Don
I will let you know what I find.

My oil pump leaked at 178 hours, I find it hard to believe both the oil pump and compressor developed an oil leak at the same time.

I have a Optimax 250 PRO XS 2009 / 2013 and I go to start it and when I turn the key I get nothing. I turn the key to the off...

Hello Don, Yes we spoke, but I took off the belt and did a better job inspecting the compressor late last night. The pulley has no " port to starboard play" as we discussed, I was just feeling the...

My main question is this, is it normal for these compressors to have a small amount of play?, it has been like this for a year.

Savage, if I open it up, are there any gasket I will need to put it back together?

Also, it has been this way for a year, which was the last time I inspected it.

I was inspecting the compressor and noticed when you turn the pulley one way to the other, it has maybe .030 play in it ( like a small...

When I did prop testing I was amazed how a different style prop would perform on different boats and even if it was the same kind of boat. If you have the time, you may gain some new prop knowledge....

MIKE, I will acknowledge that you know far more than I do on your rig and Mercury's in general. I just wanted to say that when I tested props, I have been surprised by just putting a prop on a...

Don, I have socked the area with CRC and will attempt to remove the bolt that holds it to the foot and re-ground it later. Incoming weather at the Gulf Coast may keep the boat parked this long...

Hey Don, did you get the picture?

Thanks Savage . The bolt that holds it to the foot is froze, (salt water) so it is not so easy. I can drill it out and replace it but I am not using the sensor why should I even bother?

My 2009 Optimax trim sensor ground wire broke off from the bolt that holds it down on the foot.

I am not 100% sure this is the trim sensor, it is a appx. 1 inch round device on the foot that...

Don, I just wanted to say THANK YOU.
The information and help you offer is appreciated!!

NOBODY LIKES BEING RAPED for a repair over $700.00 that a o ring would fix.

At 154 hours, my oil pump was leaking. It is hard to trust Mercury Marine when they know they have a issue and will not fix it.

Mine has been running fine with the 150:1 extra oil for 3 years now. Don, do the rings see any extra lubrication or is all the extra oil in the fuel burnt and pushed out the exhaust port?
