Great, thank you for the responses! I plan on doing these tests this weekend and then report back what I find. Thanks!

Hey Everyone, I am having a new, not so exciting issue as we are on the verge of beginning summer. I will start with a little background: I have a 1989 4.3l Mercruiser with an Alpha One Gen One in a 1989 Sea Ray 200CC. I replaced exhaust elbows and exhaust manifolds about a month ago. I...

Thanks so much Jeff! I looked on their website this morning but didn't dig deep enough. Part is ordered, now I have to be careful not to go too deep into that website, could get dangerous with an older boat!

Good Morning, Sorry for the delayed response, but you are both definitely correct. Once I took apart the top of the handle, I could see where it had broken off the throttle engage trigger. I am curious if anyone has suggestions for where I might find a part like that (a brief internet search...

Hey all, I have an older style of the Commander series throttle and when disassembling it to remove the side panel on my boat a small plastic piece came out of the vertical part of the handle mechanism. It is the shape of a comma. The throttle is off of a 1989 Sea Ray 200cc just to give the...

Okay, sorry for the delay, but other projects forced the boat to the back burner, but I finally got somewhere yesterday. I tried stretching the springs, but that didn't resolve my problem...looked like they needed it though. I feel a little silly because it ended up being such a simple...

Thanks Dennis, I will start by stretching the spring and see what I get. It may be a bit before I get an opportunity to get under the motor cover again, not looking like a favorable weekend in Maryland. Thanks again, Mike

Thanks for all the quick replies! I will replace the Temperature sending unit as that is very cheap and check the ground on the gauge to start. When I did the manifolds in the fall, I inspected the flappers and they were in good condition and in good working order. Regarding the water...

I am having an issue with my boat overheating at idle or in drive at the lowest speed (650-800rpm). It is a 1989 4.3l w/Alpha One gen one raw water pick up. Sometimes it holds at 145 degrees, but most times it will continue to climb all the way to 210 degrees. I can immediately cool it down...

Hey everyone, I purchased a zinc anode kit for my Alpha One gen 1 and I am having a hard time figuring out where a couple of them go. The fin is fine, but i am not sure the orientation of the zinc tray that goes one the bottom of the gimbal assembly. Also there are two round threaded zincs...

Hey All, I would like to thank all that have replied to this and all threads I have opened. I have successfully broken free the non OEM nuts on my motor mounts. It actually required an air chisel to break the rusted on nuts free. Once that was done I set the OEM nuts as close as possible and...

Okay, a much belated update! I replaced the coupler by building a gallows in my front yard and hoisting the motor high enough to spin it 180 degrees. The coupler is extremely easy to replace once you have the aft end of the motor in front of you...3 bolts. After replacing the broken part I...

I decided to re-pull the motor because I haven't re-attached any electrical, fuel, etc. So, I have it perpendicular in the bilge which gives me much better access to the front engine mounts. It appears the old top nuts are not OEM for this motor. I purchased new Mercruiser nuts and a good...

Thanks Jim! That is a great idea about cutting down the socket. I will find a cheap one and try this later in the week. Mike

I am having difficulty finding the right tool to adjust the motor mounts on the front of my Mercruiser 4.3l V6. I have just replaced the engine coupler and am now in the process of aligning the motor. Based on the alignment tool it appears the front of the motor is a bit low. Unfortunately...
