I have a 1985 Mark V with wheel steering. I've shopped around for various accessories, including auto-pilot, a few of which run off a 12 volt cigarette lighter socket. However, to my knowledge, the boat is not equipped with this type of outlet. Anybody have any insight and/or projects to retrofit?

Hey John,
This is great thread! You've done your homework and more than fair share of troubleshooting. From one "newbie" to another---I'm impressed with the effort and extensive steps taken (for what that's worth).
I'm also an owner of a 86' Mark V and check this forum periodically for posts that might be relevant. A few weeks ago I skimmed this one as it sparked my interest. Low and behold, this proved to be foreshadowing because now consequently, I'm experiencing the exact same issue with my engine! Ugh. Unexpected power decreasing after approx 10 ish minutes and then full stoppage.
Bleeding the air from the fuel lines seems to get her started again, but the last 3-5 attempts have resulted in the same failure. Similar symptoms also include difficulty reaching higher RPM's, as you mentioned.
So, with what seems your troubleshooting coming to an end...mine begins. I'm hoping I can learn from your experience!
I'm a little confused by your last post. If I understand correctly, RACOR is a manufacturer of filters and you [almost certainly] determined the installed part to be faulty through your most recent test. So, a replacement of the fuel filter/h2o separator should do the trick?
Any info and advice would be appreciated from your experience!
Thanks in advance,

My pressure-alcohol stove hasn't worked for a while now. Desperately desiring coffee in the morning, I'm considering making the replacement/upgrade to this propane stove:

My question, where does the propane hook up? It seems the slide-in gimbaled setup doesn't leave much room for a tank hook-up. And being the enclosed by stainless steal housing, it doesn't seem like a hose connection would be the method either. Has anybody made this installation?

Thanks guys! I received the gauge, sending unit and have other needed supplies on-hand. I read through the directions for the sending unit and understand the procedure. I'm going to attempt the job today or tomorrow. Will post pictures and results afterwards.
Still one question though. The sending unit (as gathered from instructions) seems very specific towards measurements; both related to the vertical placement of the arm, and length of the flotation device fixed to the arm. All specifications are based around the dimensions of the tank.
Does anyone have insight to this process and/or the measurements of the fuel tank on the Mark V so that I prepare the unit beforehand? It'd be great to have it adjusted to the correct specs before going down under the deck box.

Hey John,
Great response! We got the fuel filling issue resolved---I think there was small snag or clog with the vent tube. Disassembly, clean, and reassembly seemed to do the trick. We'll see if the issue reoccurs.
But more related, how did you know our fuel level gage was broken too?!?! Ironically, I just ordered the same part to do the repair as you mentioned in your post. I'm not sure the issue lies in the sending unit or the gauge. So I ordered both, and will either return the unneeded part or replace while I have the system apart.
Do you have any advice / tips / instructions for the job? I'll be starting early next week. I've been traveling, so haven't had a good opportunity to look at the mechanics and assembly of the system---I'll be going in cold.
Thanks again,

Hmmm. We do have a ongoing spider issue that we're burning to eliminate, so your diagnosis a strong possibility. I will investigate and update with my findings.
However, devils advocate: would a nesting explain why the tank accepts a small dose of fuel, but then acts as if it's full? If the vent line were clogged, my guess would be that it wouldn't accept any fuel from the start.
Anyways, this seems like a great suggestion that I'm hoping does the trick. With a bit of tinkering and exploring, I'm confident I could locate the tube and perform the check. But I'm not familiar with this type of engine or the fuel system, and it's always nice to eliminate a few rounds of trial / error when possible. Would you mind providing some more details on the location of the ventilation tube or perhaps a picture / diagram?
PS - what's the best way to exterminate the infestation of spiders?? They haven't got into the cabin much, but within a day or two of cleaning, they're all over the deck / hull!
Your help and insight is much appreciated. Thanks!

I am the new (3 months) owner of a Mark V with inboard diesel Yanmar 1GM. The gas gauge is non-functional from previous owner, so we've been conscious to monitor fuel usage. However, when attempting to re-fill, we cannot reach full capacity. After 1 gallon (or less) has been poured, a backup occurs and fuel begins flowing out from the fill port. My initial thought is that symptoms suggest there is some type of air pocket, kink in the line or ventilation issue that is preventing the fuel from entering the tank. But after troubleshooting 'the obvious', we can't notice any visual indicators.
About a week ago, the tank went dry. We had to re-fill (only the small amount of fuel the tank would accept), bleed the engine and then get back to harbor. Essentially, we're operating on a 1-2 gallon tank. We'd love the comfort of full capacity! Especially if god forbid we got into a sticky situation.
Any ideas?
