SOURCE: my tilt/trim on 1989 force 85hp outboard does not

It sounds like you need to bleed your trim lines. It is a pretty easy task and if that doesnt work you might need to rebuild your trim cylinder. I would bet on bleeding the system first.

SOURCE: how to service a tilt/trim on a 50 hp yamaha

To check the fluid level, tilt the motor up and engage the tilt lock lever. Open the bolt on top of the tilt/trim reservoir. The fluid should be even with the bottom of the bolt hole. If not add some fluid. When you put the bolt back in, run the trim up and down a few times. That should purge any air out of the system. Always be on the lookout for any leaking hoses or fittings. Hope this helped and best wishes.

SOURCE: want to replace the trim/tilt motors on my 1995

no. a unmodified transom bracket may need to be moved not removed. Since the tilt motor is out you will need to manually lift the engine. you can see the picture diagram at www.yamaha-motor.com. click on outboard motors,parts and service, view parts catalog. find your year make and model by following steps listed at top. select power trim and tilt assembly. in the picture you will see the location of the Manuel release valve on the starboard side. turn the Manuel release valve then lift the engine. tie it up or use a stand to keep it up,do not use the tilt lock. with the engine in full tilt position, you can see the motor. some brackets are modified were you can remove the motor without moving the transom bracket. If unmodified you'll need to follow these steps. (1) lower the engine back down.the steering arm needs to be removed from the steering cable and swung forward. do not remove steering arm from engine. on the starboard side of the engine you will see the steering cable going into the steering cable tube. (2)a 1 1/6 nut secures the cable to that tube remove it and slide cable out do not remove it.(3) lift engine again and secure it. your about to remove the motor mount bolt so make sure you secure the motor completely (4)remove upper and lower transom to bracket bolts remove bolts on the port side only.(5) you will see three bolt that go through the transom bracket to the trim and tilt assembly. remove them.(6) if all bolts are removed you will be able to slide the port transom bracket to the left out of the way(7) remove tilt/trim motor.

on the LEFT side of the T&T there is a screw/check valve take it out and you will find one spring one shuttle valve one more spring they come right out (needle nose) then inside you will find another check valve (you will see a small hole in the center)... use a small PIN PUNCH 1/16-3/32 and hit hit fairly hard it will spray fluid whatch your eyes. this will unlock it. refill with fluid!!! FIXED! any ?s I just did it myself Ralf 612-709-2200

Mercury outboard 70 hp 1987 when in forward gear the prop turns one way when in neutrel spins both ways when in reverse the prop is locked both ways is my lower unit working property


mercury and others have a "sawtooth" cut for forward gear so the prop will rachet spin backward when dry tested, and a square clutch dog for reverse, which when it finally engages locks the prop in reverse. and will not spin in either direction.

So when you shift--- snap in in gear-- do not ease it in gear, as it will wear the dog out faster.

Re-assembling lower unit of 40HP Mercury 4 stroke


I found a lower gear case assembly diagram at http://www.crowleymarine.com/mercury_parts/6995/240.cfm which helped me understand how the shift mechanism works. This clued me in to the fact that I was missing the cam follower rod which I then found I had inadvertently mopped up in a shop towel when cleaning up spilled gear oil. After that discovery, assembly and operation was quick and successful.

Gear shifter for 40 h. p. mariner outboard


With your lower unit off have someone shift the engine into forward while watching the gear shift select shaft's rotation,let gearshift remain in forward,now place your lower unit in forward and reinstall. In the future just put engine in forward when installing a water pump as there won't be a need to move gearshift

I have a 1976 65hp mercury outboard how do i change the oil


The drain/fill hole are the same. Put a coffee can or something like that to measure the amont of oil that comes out. Check with a boat parts, or marine or sporting goods section of biggy store. They (at least to) make a pump assembly with hose and threaded end that fits into the hole for the lower unit screw. the other part of the pump fits in a gear oil quart bottle. 80 or 90 is no matter, but needs to say marine grade or suitable for marine use. Nothing special, Penzoil for sure and I think a company Lubrite plus many others make an OK oil. Anyway, put the pump in the bottle and put back in as much as drained out. The level may be marked on the side of the lower unit. If you don't get almost as much out as you put in, check for leaky seal too.
