Greetings fellow cold water boaters. Hard to believe the season is only a couple of months away!
Having launched my 2017 37PC in early May of that year I noticed right off the bat that the port outdrive was using a lot of gear lube. This problem has continued through last season and my dealer mechanic has traced it to a bad prop shaft seal on that unit. It's now been replaced and I'm hopeful that the problem will be solved when I launch in May. I suppose it's possible that the seal was bad from the beginning or was damaged during original installation but I'm also wondering whether the 39 degree water I launched in may have played a part in ruining the seal. The dealer recommended that I use the straight 90W lube oil and that's all that's been used in my drives since new. The starboard drive has been fine, no leaks. I'm wondering, since I never operate in water over 72 degrees and usually much colder, whether it might be better to use the multi-viscosity 80W-90W lube instead of the straight weight. Any thoughts?
