Author Topic:   Trim/Tilt Reservoir fill

Earlier this week, I had need to tilt my motors up in order to move the boat on it's trailer to a new location on my property.

Both motors showed problems tilting up (to varying degrees), and both had leaked a considerable amount of fluid.

The leak doesn't seem to be coming from the trim/tilt ram seals, and I can't get it to recreate the problem - although I may now be very low on fluid.

There is a plastic cap on that is on a horizontal axis - is this the fill port? If so, how do I add fluid without spilling it out all over the floor and myself?

Any assistance would be appreciated.

The motors are model year 2000 Johnson 130 HP V-4's.

Hey Dave,

Not sure on those engines, but on my Mercury Optimax I have to have the engine in the full upright position then remove the plug on the reservoir. Then I use a plastic syringe, preferably one with a curved tip and suck it out of the trim fluid container and add it that way. Never had to fill the whole reservoir only topping off so I usually only need about half a syringe or so. Very easy to control the amount and no mess at all. Hope this helps.

Aloha,

Sean

One of OMC V4 crossflows had a similar problem. It is a 1988 pt'n't system, which I think ran for quite some time, after that. Anyhow, it had leaked out of the screw-in hydraulic fitting that held the curled hard line to the bottom of the ram... or was it the reservoir? No matter. The problem was a munged up O-ring. Easily fixed, refilled, (takes several times, cycling the motor up and down and filling again, to bleed the system), and good as gold now.

I used a lower unit oil pump to fill the trim and tilt reservoir on a 1986 60HP Johnson and a 1986 90HP Evinrude. Do a search on “Johnson outboards oil fill pumps” and you’ll find numerous sites.

The adapter provided with the oil pump I have mates perfectly on these older outboards. I’m not sure if this adapter will work on your outboard though. If you can find the correct adapter, changing the adapter is easily done.

If you purchase the OMC Power Trim/Tilt & Power Steering Fluid, which comes in a 10oz tube, you will have to transfer the oil to another container, such as a 20 oz plastic soda bottle. Be sure to leave the fitting loose so air can escape when filling the reservoir.

This search on "Johnson outboard oil fill pumps" finds about 47,000 results. Is it possible to narrow this down a bit?

Like ukuslayer, I just used a larger, cheapo syringe from Harbor Freight. I have also used a funnel with a bit of cheap plastic tube slipped over the spout, but I had to have my wife hold it for me above the level of the fill hole on the reservoir.

Not worth paying the price of a "pump" even if it's cheap, especially if you have to mail order it and wait to fix a boat you'd rather fix now.

Thanks for the responses. I use a lower unit oil pump for a lot of things, including pumping gear oil into the transfer case and differential on my truck. My concern is that this particular fill hole is angled slightly downward....it just seems weird.

I'm not sure yet if I have a hole or a bad seal or if the reservoir cap was just loose...but it seemed very strange that both had the same problem at the same time.

I'll have a chance to work in this later this week or this weekend, and will see what happens.

I'm hoping to have the cover off the boat and get started with dry-fitting the new gunwale caps so I can get that project started.

The boat will get some fresh bottom paint later this month or early next month, and then goes to the canvasmaker 30 days from now.

As I said, when my OMC v4 "couldn't get it up", it was low fluid in the reservoir. It had leaked out of a screwed-in fitting that held a hard line to the bottom. That fitting had a mangled o-ring.

I forgot to mention that you could also use a typical bathroom sink, liquid soap, pump dispenser. I've done that, too. You just keep the spout in the hole, and pump the "body" up and down. Trivially easy. Have a drip tray underneath. The combination of bleeding and dripping cost me about 4 oz. of fluid, which I finally to the the recycler on Sunday.

Let us know what you found out. I'm curious.

jimh;

The link below identifies the lower unit pump I purchased from a local marina.
