SOURCE: I have a mercury 150 optimax that I ran out of gas

Remove the plugs and blow them off and blow the cylinders out. When there is no fuel the oil injection keeps pumping the opti oil into the cylinders and can cause a hydrolock but it wont fire. Dry all of that out and you can even spray carb clean in the cylinders and blow them out to dry things up in there. When it starts it will probably smoke pretty bad for a minute but it will even out within a couple of minutes.

SOURCE: Mercury 90hp OptiMax chimes 4 beeps, turns over but

You should drain your oil tank and check your sender to see if it is stuck or if the pick up is plugged.

SOURCE: need to replace the trim/lift motor on a 225 hp

There are lots of deals on line for better prices, get exact model and year. Have a pro marine tech install it, because of liability and no loss of money out of your pocket.

Mercury 150hp Optimax outboard

many mercury motors use a rubber mounted prop on the shaft which is a sacrificial idea to prevent gear box damage and prop damage in with under water objects
what you suggests indicates that at certain load situations that rubber has failed and allowing the shaft to turn but is not driving the prop as required
It is driving just enough to give you steerage to get home

Mercury optimax 175hp, 2005. power loss at wot. RPM seams to limit at 4000. Typically with all same parameters wot rpm is 5300 rpm. Changed fuel filter..did not help

Sounds like a fuel flow problem. Make sure that there is no obstruction in the fuel lines. There may be a screen in the tank.

How do you remove the propshaft on a mercury 200 optimax once you have everything off the shaft

go google and type in-- workshop manual for mercury optimax outboard-- there is apage mercury- marine.servicemanualvault.com
which sows manual in pdf form for $4.95 a down load
run through the pages to find the transmission section and if it suits what you want , down load it and have a manual for all the items you need to do
talk with a mercury service shop and get the details of how to do it
I'm sure that you have to remove the leg from the power head so that you can get the selection lever free from the forward/ reverse dog before that gears will come out of the case

Mercury 90 hp Optimax problem

Since it's an Optimax, I'm going to have to defer to an authorized Merc service station. Barring that sounds like a fuel problem, try cleaning with some Seafoam or the Merc equivalent. I'm guessing this after is sat all winter with no love.

I HAVE AN A VOLVO PENTA D12 MG MARINE GENSET AND I HAVE ALWAYS CONTAMINATION OF DIESEL IN THE OIL CRANKASE!!!!WHAT COULD BE ?THE PRESSURE OF THE FUEL IS GOOD AND DOSN`T LOOK LIKE THE DIESEL IS CAMING FROM...

Once the fuel and oil are mixed, there is a problem with the seal of the generator set, which happens from time to time in use. It might indicates that the seal of the generator is out of order. Or it can be caused by excessive cleareance between piston and cylinder.
1. Pump membrane rot or degumming, so that diesel oil into the oil tank and oil mixing.
2. The injector has low opening pressure and poor atomization, which causes diesel oil to flow into the oil pan and oil along the cylinder wall.
3. The oil seal of the front end of the fuel injection pump is invalid, and the check hole cover of the gear chamber cover is removed.
