    81 Evinrude 25 HP - No fuel to bottom cylinder

    Re: 81 Evinrude 25 HP - No fuel to bottom cylinder Ok folks, I am curious to know if there is some secret of how to press in the lower crank shaft seal into the head assembly. Part #398051 is not the same as the original it's one of these rubber type seals and it has a lip for a lack of better...

    1984 Mariner 9.9C - Ignition Coil Spark Test

    Ok so I recently within the last three weeks or so spun the hub on my prop while out on the water and had to putt back to the dock. So I ordered a new prop. When it came in I put it on and then put the motor in a clean trash can of water to test it out. During the test trial the motor started...

    1984 Mariner 9.9C - Need new prop

    I have a 1984 9.9 HP commercial grade manual start motor with Serial 682-049356. Actually it reads 9.9M 682C-S049356 on the serial tag. When looking up props here on iboats as well as other parts places on line I can't find anything for Mariner dated before 1986. Has anyone else run into this...

    81 Evinrude 25 HP - Ignition Coil Installation

    I am in the process of rebuilding a used 81 25 HP Evinrude. The block is in the shop right now getting machined. I plan on putting new coils on when that part of the assembly comes to pass. My question is, what is the process for putting the wire that goes into the resin. I have a shop manual...

    81 Evinrude 25 HP Block Interchangeability

    I was just wondering what the range of interchangeability for an 81 25 HP Evinrude is. I'm going to take my block to a machine shop here in the next few days as it is at the very least going to need to be honed, but likely bored. As Ive searched for rebuild kits my available options are...

    Re: 81 Evinrude 25 HP - No fuel to bottom cylinder Alright, here are some photos of the crank. I didn't think it was to bad, what do y'all think. I was going to replace all the crank bearings and seals, and rod bearings regardless of what shape they were in.

    81 Evinrude 25 HP - No fuel to bottom cylinder

    Re: 81 Evinrude 25 HP - No fuel to bottom cylinder Ok that sounds good. So I got the block broken apart and pistons removed last night. See photos below.

    81 Evinrude 25 HP - No fuel to bottom cylinder

    Re: 81 Evinrude 25 HP - No fuel to bottom cylinder Ok, I got the intake cover off last night. As suspected the top cylinder looked to be in pretty good shape, but the bottom was in rough shape. The bottom cylinder deffinately has some issues, but as bad as it looks, to the touch I can not feel...

    81 Evinrude 25 HP - No fuel to bottom cylinder

    Re: 81 Evinrude 25 HP - No fuel to bottom cylinder See photo below. The area I'm referring to is at the top left, the uppermost port hole. It didn't scatch off with my nail. While I was at it I went ahead and started to remove the bolts from the exhuast cover; breaking (2) SMH, I noticed that...

    81 Evinrude 25 HP - No fuel to bottom cylinder

    When I removed the cylinder head I noticed that the bottom cylinder was dry compared to the top cylinder, so that led me to wonder what might cause the bottom cylinder not to get fuel. I read to forums, and read some posts that said it my be a stuck reed valve. So, I got to the read valve and...

    When looking up the parts for the water passage deflectors on my 81 25 HP Evinrude, it calls for (3) water passage deflectors part # 0335603, which go on the bottom. However, on my motor with the head off there are only two on the bottom, see pictures below. I only see where two are to go and...

    81 Evinrude 25 HP - Didn't Start

    Re: 81 Evinrude 25 HP - Didn't Start Well, just for fun I took the cylinder head off this weekend. Once off, not knowing anymore than I do about engines, I thought the cylinder walls looked pretty good. See picture below. I did notice that the bottom cylinder didn't appear to have any fuel/oil...
