The misfire is most notable at 1000-1800 rpm.
It also seems to have lost some top end.

Cylinder walls are perfect, the crosshatching is still...
I have a 250hpdi lower unit available locally for cheap.
My buddy runs a 250sho. Will the hpdi work on the sho? I am thinking about getting it as a back up.
If the drive shaft is different I can...
OT818984 for a serial number to get started.
I have a sportmaster and a torquemaster 1 I am rebuilding.
I am ordering gears and noticed a 859321t04 which is in my manual but I have found...
My dad installed some new prop lock for his prop. This was the first trip out with it. I imagine he did it incorrectly. The bottom has a bunch of trees so diving in is difficult.

We lost a 5 blade prop in the lake. The spot shows to be 11 feet deep on the sonar. By the time I took the screenshot the boat had drifted into 5 feet.
The boat was in 5.4 at the time of the screenshot but the image was in 11 feet. That area is full of trees

I lost a 5 blade prop in the lake. I went and charted the area and found what I believe is the prop. I am calling on the experts to confirm.
Maybe you need the old reed switch? If the old one is normally closed and the new one is normally open that could be the issue. The only other idea I have is to have that switch command a relay...
Dual console and it has a 10 inch jack plate.
Thanks for any help!
I have a 250xs ecu if you want to see if any gains would be had by running one. I will loan it to you if you want.
The standard proxs and torquemaster driveshaft will work. The new "wingmaster" will not as it has different pinion splines and a larger shoulder by the water pump.
If the pulse pump is good, and the fuel lines are not collapsed, make sure the lines are all tight. I have seen lift pumps not able to "lift" because of a small air leak due to a loose hose clamp. ...
Look at your coild and see if one appears to be oozing marshmallows out of a crack. Mine had a failed coil and it blew the same fuse. The white, fluffy stuff helps track it down.
Otherwise go...
I believe it is to allow more air flow into the throttle body. I noticed the same thing. I doubt cutting tjat hole on a 250 will help, if that is what you're thinking.
Check the coils closely to see if one appears to have marshmallows oozing out of the case.
The 250proxs and the 300xs have the same trim setup so it should work if it fits the 225 and 250. Unless you have the HD offshore mid with a single ram and remote mounted trim pump.
Sei sells garbage knockoff mercury stuff that has the same dimensions and spline counts so i used one of theirs for comparison.
It showed the spline difference and the thicker seal surface.
I...

Look at this one.
It has the groove in the thick portion like the one i have and it has the larger sealing surface.
I have done it before it is the same. Some have a 3 wire and some have a 2 wire motor for the trim. Check that.
Maybe the shop was using the bottom port to apply the vacuum and pressure and therefore sealed the leak while testing for it? Then reinstalled the leaking drain plug?

Is my engine's serial number. We can use this as a base since my sportmaster internals are the same as the torquemaster. 1.75 fat shaft 20 inch
