Hydraulic tilt question

I bought a boat about 3 years ago that has a 1989 40hp Evinrude with a built-in hydraulic power tilt system. It has worked fine until recently when it started acting really sluggish and sounding weak to raise the motor. At first I thought the battery was weak, and it was a little low, but even when fully charged it acted the same way. I checked the fluid and it's full, but I don't know what else to do. Lately it may work, sluggishly and weak sounding, for one or two cycles up and down and then just quit and not work for several minutes.

Does this mean anything to anyone? If not, would the place I usually bring the motor for service be the place to go?

Thanks!

It's the electric motor on your power tilt. You can have a shop (not boat shop) rebuild it or replace it with a new one but will be expensive.

If you can DIY some, you can open it and check brushes, they might be worn out or plain dirty.

First thing is make sure the battery is good and fully charged. Next is check the battery connections and then the connection at the relays and switch(s)

If they all check good then I'd say the brushs in the motor are worn or hanging up. A electric motor/alternator shop will be able to help you there. One way to trouble shoot the motor is trace its pair of wires from the motor to a relay, disconnect that pair and and connect to a battery.

Why ? Do you know of anybody that had problem with his boat at the landing ? I've never had that happening to me, I am a FM Pro...... grin.gif

We spend countless hours telling people what to do and how to get ready, I don't think you'll ever see us from FM "caught with the pants down" at the landing..... grin.gif

Not many people can carry an avatar like mine.....

my guess like Surface tension says.. you probably got a dirty trim eng.. and you can as stated, try a do it yourself or have a shop do it. On many motors, to get to all the screws to take it apart you need to remove one side of the motor mount, depending on how big an eng you have this can be easy or in my case (merc 175hp) it was very hard!!!! VERY HARD!!!.. however, I cleaned the brushes and put it back together and it still works great and that was about 5 yreas ago.(I sold that boat, but stil know the guy who owns it.)

Dietz, I had a 150 Evinrude where I replaced a brush spring with....a ballpen spring. I was at a resort with no shops around and I intended to use all my days left.

It worked great for 2 more yeras then I sold the boat.

Thanks for all of the advice guys. I'm fairly cabable at trying to do things myself, but electrical motors are foreign to me. So much so that if I took it apart and thought the brushes looked dirty, what would I clean them with? I called around and talked with several people, most suspected that it was worn-out, shot. No one actually mentioned it could just be dirty. The electric motor itself is $230-250, one guy will get me the motor and I can put it in, the other places want to put it in themselves. I might have to look inside and see.

Question: If it's dirty, would it just plain quit? Yesterday it wouldn't even make a sound.

Thanks a bunch!

Take it apart and see what's wrong, could be a brush spring is melted or rusted out (like mine) or stuck, or the rotor dirti like the brushes.

I used brake parts cleaner if I cannot find any electric parts cleaner.

You can take it to a electric motor repair shop, it should cost around $ 50/$80 to have completely rebuilt. If you ask a dealer it will charge you an arm and a leg, they are notorious to cost a couple of hundred, which is way too much. You can buy a whole good used complete tilt unit on Ebay for $ 200

Well I finally had the time to try to fix this thing. I took it off the boat...what a job that was! I swear they build things so it's near impossible to do yourself. Looking back I probably could have left it on, but initially I was assuming this was a replacement situation. Anyway, I opened it up and it looked pretty good except one ground was corroded. I fixed that and cleaned it up a little, plugged it in and it whirred like new. Another 1.5 hours putting in back on the boat, filled it with fliud and it works like a charm. I hope it lasts!

Thanks guys, you helped me save $280 on a new electric tilt motor.

      Big Traverse Ice Free

      By LakeofthewoodsMN · Posted

      On the south end...   The big basin, otherwise known as Big Traverse Bay, is ice free.  Zippel Bay and Four Mile Bay are ice free as well.  Everything is shaping up nicely for the MN Fishing Opener on May 11th. With the walleye / sauger season currently closed, most anglers are targeting sturgeon and pike.  Some sturgeon anglers are fishing at the mouth of the Rainy River, but most sturgeon are targeted in Four Mile Bay or the Rainy River.  Hence, pike are the targeted species on the south shore and various bays currently.   Pike fishing this time of year is a unique opportunity, as LOW is border water with Canada, the pike season is open year round. The limit is 3 pike per day with one being able to be more than 40 inches. All fish 30 - 40 inches must be released. Back bays hold pike as they go through the various stages of the spawn.  Deadbait under a bobber, spinners, spoons and shallow diving crankbaits are all viable options.   Four Mile Bay, Bostic Bay and Zippel Bay are all small water and boats of various sizes work well. On the Rainy River...  Great news this week as we learned sturgeon will not be placed on the endangered species list by the U.S. Fish and Wildlife Service.     The organization had to make a decision by June 30 and listing sturgeon could have ended sturgeon fishing.  Thankfully, after looking at the many success stories across the nation, including LOW and the Rainy River, sturgeon fishing and successful sturgeon management continues.   A good week sturgeon fishing on the Rainy River.  Speaking to some sturgeon aficionados, fishing will actually get even better as water temps rise.     Four Mile Bay at the mouth of the Rainy River near the Wheeler's Point Boat Ramp is still producing good numbers of fish, as are various holes along the 42 miles of navigable Rainy River from the mouth to Birchdale.   The sturgeon season continues through May 15th and resumes again July 1st.   Oct 1 - April 23, Catch and Release April 24 - May 7, Harvest Season May 8 - May 15, Catch and Release May 16 - June 30, Sturgeon Fishing Closed July 1 - Sep 30, Harvest Season If you fish during the sturgeon harvest season and you want to keep a sturgeon, you must purchase a sturgeon tag for $5 prior to fishing.    One sturgeon per calendar year (45 - 50" inclusive, or over 75"). Most sturgeon anglers are either a glob of crawlers or a combo of crawlers and frozen emerald shiners on a sturgeon rig, which is an 18" leader with a 4/0 circle hook combined with a no roll sinker.  Local bait shops have all of the gear and bait. Up at the NW Angle...  A few spots with rotten ice, but as a rule, most of the Angle is showing off open water.  In these parts, most are looking ahead to the MN Fishing Opener.  Based on late ice fishing success, it should be a good one.

      Nice fish. I moved to the Sartell area last summer and just thought it was windy like this everyday up here? 🤭

      Crazy windy again today.... This is has been the norm this spring. Between the wind and the cold fronts, fishing has been more challenging for me than most years.  Panfish have been moving in and out of the shallows quite a bit. One day they are up in the slop, the next they are out relating to cabbage or the newly sprouting lilly pads.  Today eye guy and I found them in 4-5 ft of water, hanging close to any tree branches that happened to be laying in the water.  Bigger fish were liking a 1/32 head and a Bobby Garland baby shad.   Highlight of the day way this healthy 15incher
