I recently upgraded the ignition system on my 1989 300WE 5.7 to DUI HEI distributors. I have the distributors, coils, and Thunderbolt IV modules available. Also new Mercruiser caps and rotors, one set unused and the other set has about 20 hours on them. When one of the engines lost spark, I...
I recently located an old school non-digital timing light and printed out some timing tapes to attach to the harmonic balancer so I could check the full advance. The old school timing light was also telling me 39° advance at idle, it should be around 8° BTDC.
I'm absolutely sure that I'm...
I recently replaced the distributor caps and rotors on my 1989 300WE. The rotors were seized onto the distributor shafts and very difficult to remove. It was necessary to crank the engine to rotate the distributors in order to pry up on the rotor from opposite sides. This was done with the HT...
I'd like to replace the sanitation hose the runs between the toilet and the holding tank on my 1989 300WE. I'm looking for some tips from someone who may have some experience with this. The holding tank is on the starboard side aft of the fuel tank. The hose is fairly accessible as it runs...
My 1989 300 WE has the rigid straight blades that are bolted to the arms. I replaced the blades, but one of them doesn't work for crap, as I think the windshield isn't perfectly flat. I'd like to change the arms to a conventional hook type that will accept a common curved windshield automotive...
As it turned out, the hoses are 2-1/2" ID. Bought the Buck Algonquin hose, which is has a much thicker wall than what was on there. Also bought the Buck Algonquin T-bolt hose clamps.
Removing the flanges with the Buck Algonquin puller was definitely a struggle, but they came off with a little...
I have purchased (3) Attwood 9067-1 battery boxes. Hopefully it won't be too difficult to get down in there to remove existing and install new hold down anchors.
My 1989 300 WE has three batteries in a single row between the engines. All 3 batteries have have threaded studs and conventional large diameter lead posts on both positive and negative. All of the connections are made to the threaded studs with the positive cables having your typical plastic...
I was able to source one from http://www.thebrassworksinc.com/
I haven't been able to try it yet and my partner has the original, so I don't know for sure that it works, but it looks right and they both have "13" stamped on them. $15 + $7 USPS shipping
I know this has been covered in previous threads, but they are all quite old and the pictures are MIA. My research leads me to believe it was originally provided by Bowmar. I'm looking for a duplicate key, any suggestions?
I'm looking to correct the "loose" steering on my recently purchased 1989 300WE:

I contacted someone at dometic/seastar/teleflex:
Assuming that the helm and cable are 30 years old and somewhat worn, what would the...
I looking for some clarification on the batteries and charging system on my recently purchased 1989 300WE. The owner's manual has a bilge layout diagram which correctly shows 3 batteries in a row between the engines. I'm assuming that there are 2 engine batteries and 1 house battery. There's...
