Hey ! Can someone confirm the torque value for the engine mount bolts/nuts @ 50ft/lb upper and 90ft/lb lower on the LOCKNUTS?
It is for the mounts that come on SN:1B887210, 250 Pro XS. Reason I am...

I’m keeping it incase i ever add a bracket i have the mid to swap back on.

Thank you guys so much for your help! I love it here:beers:

Will it work with my current PCM? i don’t care about the sound, i just want to make sure the engine will be okay without the relief over the plate.

After all the issues i had with another 250 pro xs i had (my other thread), i have bought a new to me 2011 250 ProXS 20”(SN:1B887210) with 120 hrs but the issue that i have is that the engine is 20”...

Attached are pics of the oil pump, all plunger o rings are intact and there was no blockage inside the holes. The only thing i found was some light corrosion on...

Attached are the pictures requested. I noted significantly more oil in the #5 compared to #6 cylinder. These are all pictures of #5cyl, today i checked the oil lines again and didn’t find...

Yes that was the new piston, first rebuild lasted 4HR, second rebuild (pictures shown) lasted 9HR.

Melted #6 both times.

I pulled them off i’m gunna have them checked again locally just incase.
For clarification, i replaced the air injector on the #6 after the second rebuild + another injector that was “flowing too...

Attached are the pictures of #6 piston, piston pin, needle bearings of the piston, and the cages and roller bearings of the crank on the #6.

The bearings were wet with oil when i removed them. ...

Could the oil pump be failing to provide oil to just one cylinder or an oil pump failure would affect all cylinders?

I blew the lines back from the cylinder to the plenum, but i will check them with a flashlight when i go back on saturday. I am also going to change all the oil lines, any idea where i can get them ?

Anything else that you guys suggest I check while i’m there ?

I will get the pictures saturday when my work week is over and i’m able to head to the shop. Overheating is out of the question I have my analog plus my mercmoniter gauge that i keep a close eye on...

Backstory: I have a 2010 250 pro xs i bought used, running fine but the engine had 95psi across all 6 cylinders, i decided to rebuild it locally and after 4 hours of runtime it melted...

@Don the engine runs fine, i pulled the injectors off to clean and i pulled the diaphragms and one had the lip pinched from improper installation and the other had the very lip squished but still in...

Hi all!

I was wondering if anyone can provide me the PN of the two diaphragms on the LH Fuel rail and which pn goes in which position. Thank you in advance.

thank you guys !

I just wanna know if my internals will work on this sportmaster case! thanks

Hi! I have a 2010 250 Pro XS (sn:1B787856) with a verado(i believe) lower unit with the fill plug on the RH side. I have a friend with a sportmaster case unsure of the year, can i swap the internals...

So i installed a clear line with a barb on the fuel line that goes to the VST to check for air in the system and sure enough i had BIG bubbles accumulating in the clear fuel line. Upon further...

My boat requires 25” with the setback i currently have, it’s still adapted to 25”. Im going to run a new fuel line exactly how the FAQ specifies and go from there. I’m also going to eliminate the...

Hi I have a new to me Opti i have been having issues with. The engine misses a little bit at idle after extended periods of idling in a channel. I’ve noticed that while i’m cruising...

Thank you Don ! I ended up buying the engine, runs great. Maintenance is coming up next so i’m hoping to find extensions in the lower unit upon water pump replacement.
