Water in lower unit
I have a 25 HP Johnson that keeps getting water in the lower unit, however there is no apparent leak of lubricant. Any ideas where the water is coming from?

Thanks I'll check it. I have usually found fishing line in the ones I've had to replace

As we know, seals can leak from both pressure and from vacuum. Chances are, when warm, the seals work fine under pressure. After cooling, vacuum is created, and then water is sucked in the seal. This is why no oil is seen on the water around the outboard.
If you have anything close to a 1970 Johnson, e-mail me and I can send a 20 hp Johnson manual for you to look at. Most are similar, for you to compare and use for reference.
