I am removing oil injection system from 2001 50 hp 3 cylinder 2 stroke. Will not having the oil level sensor plugged in cause the engine to go into limp mode or cause a warning horn to sound? Finding mixed answers to this. Thanks

I also would like to know if there is room to pull out the oil pump driveshaft with powerhead installed?

I have a 2001 yamaha 50 hp 3 cylinder 2 stroke. I bought it recently but the oil pump arm was not connected and the level sensor was unplugged. The seller didn't know much about it. If I pull the oil pump off does anyone know a part number for a block off plate and seal to put on the engine...

Ok thanks I'll check it out

Working on lower unit 2001 mercury 90 hp six jaw reverse. 3 cylinder 2 stroke. Does the driveshaft slide out after removing water pump assembly? If not what needs to be done to remove the driveshaft from the lower unit?

****. I just sold the v6 gearcase as a parts only item on ebay for 200.00 because I thought something was wrong with it. Oh well someone got a heck of a deal. Thanks guys for the info I appreciate it

Thanks everybody. Wound up buying 2 25 hp parts motors. I swapped the whole short shaft lower unit and water tube to make this a short shaft motor. Came out great.

I have 2 lower units. One is a v6 lower unit one is a v 4 I noticed they both have play when wiggling driveshaft side to side. Noticed with and without water pump and housing either installed or removed. Gear oil looked fine. I pressure tested the v6 lower and couldn't get over 2 psi as I hear...

I have this v6 lower unit but the end of the propshaft splines look strange. Anyone see this before? What could cause it? Will it work ok? Thanks

Thank you. I appreciate it

I have a lower unit I bought with a bunch of parts. I can't find a part number anywhere on the housing. They are usually on the casting near where the exhaust enters from the midsection. I want to sell it but I don't know what it is off of. There is a number on the driveshaft of 339769 but I...

great, thanks for the tips

I have a 1980 evinrude 25 hp 2 stroke tiller longshaft. Need a lower unit (above prop exhaust split gearcase style) anyone know what years interchange with this? It uses a long stud with a nut on top as one of the mounting attachments

I also pulled the reeds and shined a flashlight into the carb opening. I can see a decent amount of light when viewing the ends and sides of at least 2 of the reeds for the bottom cylinder. The top cylinder reeds also show a little light but not as much as the bottom ones.

As a test I pulled the shrouds which exposes the upper part of the driveshaft where it enters the crank. I sprayed a decent amount of wd40 through one of the reeds on the lower cylinder and none of it came out from the bottom of the crank area. Is that a good test?

Working on a 2001 2 cylinder 50 hp 2 stroke Johnson. Top cylinder compression 145, bottom 130. Sounds like running on one cylinder and a lot of gunky sludge coming out of exhaust (unburned oil/fuel) Top spark plug shows normal discoloration bottom cylinder spark plug looks brand new (both plugs...

I'm working on a 2001 Johnson 40 hp 2 stroke 2 cylinder. Swapping powerheafs. One of the powerhead bolts was seized and snapped off. I was able to drill out the broken remains and retapped the hole. Problem is I wasn't straight on so now the bolt is angled so bad that the new bolt doesn't engage...
