Leaky tilt cylinder?

8 posts in this topic

I have a 1986 90hp Merc that I believe has a small leak in the tilt cylinder. The motor will slowly (imperceptible actually) lower itself. I've topped off the fluid and searched up and down for repair kits or procedures. I'm coming up with nothing though.

I figure I could pull the tilt/trim assembly off and take it into a hydraulic place to fix, but now that the season is upon us, and I have wasted the last month or so piddling around with it, that doesnt seem like a good option. I know I could also put a new tilt/trim assembly on as well, but that is too expensive.

Anyone have any advice/experience? I can't find repair kits for the hydraulic cylinder. Can anyone recommend a hydraulic shop in the cities that I can take it to when I'm willing to be without my boat for a while?

It isnt a big issue, more of an annoyance. It has been this way since I have had the boat (5 years now) and hasnt gotten worse. My worry is that it will get worse, and then I'll be hosed.

Thanks in advance,

Dan

here is another place, they have a few locations in mn

Catco parts Roseville

One thing that i have found when dealing with older cylinders, they may be able to match the cylinder with an aftermarket much cheaper than rebuilding it. Most big shops can make a kit out of parts on the self. Hope this helps, let me know if they can do it. Jeff

I presume you've verified that the manual bypass screw is tight?

Thanks guys. I will check those places jeffreyd - I didnt want to tear it apart without having a plan to get it back together. Not the right time of year to be without a boat!

marine man - where is the manual bypass screw? I did not run across that in my manual or things that I checked.

I did not even think about a bypass, but if it were open would you not have some type of oil seepage? I am thinking of a regular hyd cylinder so you could bleed it down if you had to. It almost sounds like the internal seal is leaking by allowing the fluid to push back. Marine man, is there some type of safety device in the system that would include a holding valve etc?

No you wouldn't have seepage.. it's a internal bypass valve.

It's a big flat head screw, usually found on the lh side of the motor, with a cutout in the engine mount (that mounts the boat to the transom). Make sure it's tight.

    • Sounds perfect, thinking your guys reviews will seal the deal for me once I can see one in person again, a hyfax kit will also be on my list as I plan on pulling it behind my sportsman 570. Thanks for the review also AAmerican, it's early to be thinking ice fishing but I'm sure there's people out there like us that are a little anxious!
    • The Chippewa flowage would be a great place to start. I will be honest. Walleye are not what I have ever chosen to Target when I fish up there but the flowage is a great fishery.    Nelson lake would be another choice.
    • I have had 3 of the otter pro xt's, a cabin, lodge and resort. I still have the resort and recently purchased the cabin. I have not had many different brand portables but have fished in other brands buddies have. They are the nicest portables I have personally owned and until I try something I like more I wouldn't change from them at all. The resort is heavy and not something I like dragging far by hand especially loaded with gear and much snow on the lakes. But it has tons of room and I have fished 4 people in it before, a little tight but doable. The cabin I purchased for more hand pulling and an extra for if I have people along. They are very warm and I have fished in them down to -30 deg F. A regular buddy heater keeps them plenty warm, if it isn't to cold or the house is banked well its easily t-shirt weather inside. The resort needs a big buddy heater for colder days sometimes due to the larger size but isn't terrible with a regular. Overall very happy with them all and have been very durable. Also no dripping of water from the ceiling. Highly recommend a set of hyfax for the bottom. I had over 1000 miles pulling my old lodge and they hyfax held up great but I always pulled on snow and not across asphalt much at all.   Changes I have made to them: - added a battery box and inside LEDs  - used stainless screws on the band that hods the fabric to the tub only because I don't like the look of the rusted screws.     If you think you'll be purchasing one I would recommend stopping at a Gander Mountain if you have one near by and getting a set of hyfax since they are going out of business there is a good amount of ice gear. I found hyfax recently there for $15 a set.
    • We are on Lake Edward at WildWoods RV resort just north of Merrifield, MN. It is nice just driving up, unlocking it, playing for the weekend and locker her back up and leaving the frig on.  They let Atheists and Jesus freaks all in!
    •   My wife and I are starting to think about parking ours someplace. I'm tired of trying to get reservations and having to hook and unhook and all that goes with a weekend of camping. Plus I would like to have the toys available like 4-wheeler and boat.   We are looking at places up north. We know several people and like the Emily-Outing-Remer-Hill City area. I think you a further west, right? Brainerd area maybe?  
    •   5 years at one campground until they went private and wanted 60-70g's per lot with one-just-like-silly-me-o-en fees which were about what we were paying yearly already on top of that!  12 years where we are now with way bigger lots.
    •   Too bad the previous owner didn't know what they were doing. Never, ever use silicone on a rubber camper roof. I learned that the hard way many years ago.....   At least you have a good reason to have to go to the camper this weekend    How long have you been doing the seasonal thing?
    • Thanks for the reply, sounds about like what I expected and I really like the square tubing on the otters compared to clams round cheaper setup. Anyone seen any changes to the new otter lineup for this year? 
    • Last weekend spent some time re-sealing a small seam leak on a trim edge. Found out the owner before us had a leak on the same trim edge spot and left out a screw!! Also washed down the canopy and the ever reoccurring black streaks around the roof edge.   This weekend may go back and clean out and reseal a few other areas the passed own made a mess of sealing with sillycone! Using Butyl rubber this time as silicone can be pulled right off after a few years.
