    Part name for the fuse and assembly next to ignition. 1985 Mercruiser A1G1

    K, I got mislead by the “it cuts out" comment. Just match the hole diameter and the fuse size (larger is ok) Here is an example fm AZ link

    Starter issue

    Useless the OP found the head of the valve (or pieces thereof) inside that chamber, it got chewed up and spit out. This is a real mystery: was running fine and then on the next try cannot start, in fact did not even turn over, only a ‘click’. So, no time for that valve disc to be chewed up and...

    Part name for the fuse and assembly next to ignition. 1985 Mercruiser A1G1

    If you mean the glass fuse inside the holder keeps blowing, then there is an issue with either the size of the fuse being installed or the current draw on the circuit. Or do you mean that the fuse holder itself needs to be replaced?

    Starter issue

    Well, its decision time. If I may, please consider the following: Rebuilding an engine can be very satisfying and provide lots of bragging rights. If you have kids of the proper age, what fun to get them involved Unless you have a hull integrity issue, fiberglass boats last practically forever...

    Testing plug condition

    Looks sweet, congrats on the build. Pulling plug wires one at a time is a time-honored way of initial troubleshooting. One concern to be aware of with this high voltage system is causing an arc inside the distributor cap that can be an issue (that spark is going somewhere!). Once you are done...

    Volvo Penta 5.0 GL PWTR - severe overheat - thought I was on fire - troubleshooting Questions

    Good on ya for not wanting to pass along hidden issues. So, I would do this: Dye Pen the block > this way is stays in the boat (less cost) and provides a reasonable check for cracks. If found, post pics as It may be too detrimental to put on remain heads, ie now selling the boat with a busted...

    Volvo Penta 5.0 GL PWTR - severe overheat - thought I was on fire - troubleshooting Questions

    Goose, Once you decide on the level of cash you are willing to spend it will dictate what you do. Back in post #14 your concern was not dumping lots of $ into this boat. No issue with that whatsoever. This is why I was suggesting look for any obvious issues (like that crack) and if none go for...

    Volvo Penta 5.0 GL PWTR - severe overheat - thought I was on fire - troubleshooting Questions

    Some additional thoughts: for the reassembly, chase ALL the various bolt holes with thread chaser (not tap). This is important to get the proper torques. Example thread chaser set (link). Also get a machinist straight edge like this link. Lay it across the various matings surfaces like the heads...

    Volvo Penta 5.0 GL PWTR - severe overheat - thought I was on fire - troubleshooting Questions

    Agree and Amen. With 21 years myself in the Navy I have known too many that have given their all. For your pics: others like Lou will know better, but it sure looks like you have led a good and clean life because someone it looking after you! Assuming it is debris in the cylinders (as opposed...

    Mercruiser 120 poor starting

    Wow, that is a lot and while may not preclude the engine from running its good that the engine did not run with that mixture! That much fuel must have been coming from the leaking diaphragm of the fuel pump. So new pump and condenser and lets get it running!! BTW I meant to highlight that was...

    Mercruiser 120 poor starting

    Guffer, I am not quite following the test you are doing on the fuel pump. You are correct in your thinking that perhaps the diaphragm of the pump is leaking and introducing fuel into the oil. Below is a diagram of a generic mechanical fuel pump. It needs to be “airtight” (i.e. leakproof) in the...

    Volvo Penta PJX jet drive

    Fun little boat! Some other things for your son to consider if I may. Do not use Automotive replacement parts on the engine. It will be the less expensive way to go but for things like starters, alternators and other electrical they will not be SAE J1171 compliant. In fact, this may be a good...

    No start after engine install. Need Help!!!

    Roger that. The point of the post was around the TBV and how the testing process needs to be different fm TBIV so was trying to mockup the TBV to show why. I could not find a wired up TBV pic readily so stole with pride fm another post :)

    No start after engine install. Need Help!!!

    Jonny, We should have picked up that for the version “V” of the ign system bonds the 2 gray wires inside the wiring harness as Scott mentions, thus only one gray wire to neg post of coil. Sorry for that. Thus, the T/S guide does not work for version V unless you disconnect the plug at the...

    No start after engine install. Need Help!!!

    Jonny, Please pardon my dog piling on this one. First some fundamentals: The Ign Coil has +12V on the + terminal (so when the key is on / start it has power) and on the other side (the negative terminal) is a switch that opens and closes as the motor turns. When the switch is closed the coil...

    93 mercruiser 4.3 alpha one gen 2 fuel problem (I think)

    It’s past my posting time so this may be a short answer Warm up time of engine and type of choke are not related. It alway takes time to warm up based on lots of factors including intake water temp. I would leave choke as stock (not convert) as it’s one less thing to worry about once you get...

    93 mercruiser 4.3 alpha one gen 2 fuel problem (I think)

    Before addressing how to power an electric choke, can you explain more about taking the carb in for a rebuild? Did you remove the carb and take it somewhere? Or took the boat somewhere and they experienced the same conditions as you did and said, “it’s got a lot of build up and sticking”? Build...
