    '94 Yamaha 130TXRS. Trims up only when stopped/slow.

    I inspected the seals around the rods. Everything looked clean and dry. No leaks apparent anywhere. I tried sitting on the lower unit while I raised and lowered the motor (just to add a little resistance). Made no difference. It went up and down perfectly. The neighbors must have thought I was...

    '94 Yamaha 130TXRS. Trims up only when stopped/slow.

    Good question. I never realized the distinction between tile & trim. Now I know. Thanks. I'll check this afternoon, but I suspect it is the limit of the trim rams. It's on the trailer. I'll see if I can tell.

    '94 Yamaha 130TXRS. Trims up only when stopped/slow.

    I just filled the reservoir a few days ago, and bled out all the air. Seals look ok. I will try again today. But, if either of those issues were present would it account for only not working when under way? When stopped it operates up & down completely normal. As soon as I start moving it will...

    '94 Yamaha 130TXRS. Trims up only when stopped/slow.

    Recently topped off trim fluid when trimming was sluggish. That solved the problem. Now though, the motor trims up only when going very slow or stopped. As soon as we get moving a little, both before and after getting on plane the motor only trims up mayby 25%. It will not go higher. As soon as...

    Stripped Threads on trim Cylinder....

    While bleeding the trim cylinder lines I discovered that one port was so far gone (corroded) that I could not get the line re-attached and ended up stripping the threads. It's aluminum and I think I'm basically screwed (pun intended) and need to replace the cylinder. But.... is there any...

    Overheating at WOT. Not the usual solution....

    I have a 1982 Mercruiser 470. Since I got it a couple of years ago it has been overheating at high revs. (over 200 degrees F.). I know this engine has a history of problems, but this one has had most of them fixed already- new alternator, new 4" heat exchanger, etc. I replaced the cam seals 2...

    Replacing the Water Pump Cam Seals on 1982 Mercruiser 470 -Day One

    Re: Replacing the Water Pump Cam Seals on 1982 Mercruiser 470 -Day One Had a chance to work on the project over the weekend. All going well. PVC couplings fit perfectly for installing the new seals. (Placed cover on a towel on the cement floor and the seals went in fairly easily. Second pic is...

    SAE 40, or 20w-40 motor oil...Hard to find

    1982 Mercruiser 470 engine. My manual says use "SAE 40" oil, a straight-weight since I'm in a warm climate (over 50F temp. SW Fla). Also says optional 20w40 or 20w50 is possible but not preferable (Aslo hard to find). Strraight SAE 40 is not turning out to be very common, even at stores like...

    Replacing the Water Pump Cam Seals on 1982 Mercruiser 470 -Day One

    Re: Replacing the Water Pump Cam Seals on 1982 Mercruiser 470 -Day One Beginning of "Day 3". (at least the 3rd day of working on the repair. Some days I have to actually do "earn a living" work). Re: Anti-freeze. Everything I read says that in a tropical climate (I'm in SW Florida) anti-freeze...

    Replacing the Water Pump Cam Seals on 1982 Mercruiser 470 -Day One

    Re: Replacing the Water Pump Cam Seals on 1982 Mercruiser 470 -Day One OK. Here is the start of Day Two. (I'm keeping this as one thread). The stator is off. I got one of the frozen bolts off, but had to cut the last one, and then break it off at the block. It was trashed: busted magnets...

    Replacing the Water Pump Cam Seals on 1982 Mercruiser 470 -Day One

    Re: Replacing the Water Pump Cam Seals on 1982 Mercruiser 470 -Day One Good question. It connects on the VR (purple wire) with the red wire (wiring diagram says orange). It goes up into the wireing harness so hard to tell where it comes out. Here's a pic and the wiring diagram. Yes wiring...

    Replacing the Water Pump Cam Seals on 1982 Mercruiser 470 -Day One

    Ok. Here?s the start. A 1982 Mercruiser 470. I just bought this as is. Don?t know much history other than it overheats at high rpms. I cleaned out the manifold, elbow, replaced the thermostat and the exhaust shutters. Before the test drive I found a coolant leak out the water pump weep hole. So...

    Replacing the Water Pump Cam Seals on 1982 Mercruiser 470

    I am going to replace my cam seals on my 1982 Mercruiser 470. I am ordering the parts tomorrow and will probably start disassembly this weekend, and re-assembly next week, after the parts arrive. But I have a couple of questions first. I have had water only in the engine now for a...

    How much time w/ coolant leak problem?

    I have a 1982 Mercruiser 470 #6180420. It seems I have coolant leaking from the front of the motor. Looks like I need to do a repair on the seals and camshaft. Got that. Question is: is it still safe to operate for a little while? I don't think it's been leaking long, but I need to do some trial...
