About a year ago I developed a problem with my 89 Mercruiser. Almost every time I run over 2500 RPM or so, the heat alarm goes off. My temp gauge does go up a little when this happens. So far in an effort to solve the problem I have replaced the Seawater Pump, Circulator Pump, Thermostat, both...
I have a 1989 Mercruiser 5.7 driving an Alpha One/Gen one.
The past few weeks, when I accelerate and approach 3000 Rpm, SOMETIMES the alarm sounds. as soon as I back off the alarm stops. I am running a 140 deg thermostat. under normal slow running, the temp gauge reads about 145 deg. when i...
I've got an 89 Mercruiser Alpha 1. i have an ongoing problem keeping the shifter level tight. there is a set screw underneath the lever. i dont think i can get that any tight. if i loosen it then tighten...it seems to me ok for a few hours of operation then gets sloppy to the point that you can...
I've got an older Alpha 1 Gen 1 drive. I'm having a problem with the shift lever coming completely off the control. it seems this just has a friction fit on a flange in the box. is this correct? if you push on it when you move it, it's fine. or if I remember to keep making sure it's pushed on...
I have a 1989 Mercruiser Alpha I Gen I Stern Drive. I need to replace the port side trim cylinder. It seems that there are 2 different length tubes. I did a measurement (under water) over the weekend. I came up with 16 1/4 to 16 1/2 inches. The sales guy says that most 89s are the shorter...
I've got a 1989 Alpha One Gen I outdrive. I found out yesterday, when I splashed the boat, I've got a hole in my port side tube. The boat is at the marina 100 miles away. I've contacted a few vendors and they tell me I must measure the cylinder to determine the correct model. At the same time, I...
I may have posted this request for info before, but I still havent got it figured out.
I have a new Mercury 3.5HP 4-stroke outboard. The first 15-20 hrs it ran perfectly. This motor only has the internal 1/3 of a gal tank, so I carry a gallon can and fill it when it runs out. I was out crabbing...
I have an 89 Merc 260 with an Alpha One. The control lever is really sloppy. Seems like it's loose as in from side to side. Before I tear this apart, it there a way to tight it up, or do they wear to this point?
Before I take this motor back to the dealer (because I probably wont see it again till Winter) I thought I'd run this by you guys. I recently bought a new 08 Mercury 4-stroke 3.5hp outboard for my fishing boat. The first 2 times out with it, it ran flawlessly. I had it out last weekend, ran...
I'm having a heck of a time trying to remove the upper vent screw. I had a little elecrolysis issue last year and I guess it got to this screw. I've tried all the normal stuff. PB Blaster, Freeze Off, Bigger screw driver, Anything else I can try? I'm afraid to take a drill to it for fear of...
I bought my first new prop.Mercury Black Max came with Flo Torq II hub kit.
I'm a little confused on the nylon sleeve. I cant tell from the drawing which end goes in first. The second thing is it will not go in easy either way. Is it normal to have to use a rubber mallet to drive into the prop...
A friend of mine just bought 9.9 Johnson. We think it's a '96. No Spark either cylinder. He's not sure if he wants to start throwing non-returnable expensive ignition parts at it to fix it. Are there any common issues with this motor? I was reading some of the older posts and I saw mention of...
I have a 1989 350ci 260hp mercruiser.
My alternator has been getting a little funky on me the past month or so. Every now and then it would start cranking out about 15.5v. Then it would return to normal. Always just right or too high. Well, was heading out this weekend and it started dropping...
My guest shore charger died this year. It was designed to charge 2 different banks of batteries. I also have a Perko 2 battery switch. 2 new Deep Cycle batteries.
I have a new charger, the automotive type, that is automatic 12/8/2 amps. I would like to mount this in place of the Guest charger...
