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 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...

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 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 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...

I believe that my 1989 300WE shaft stuffing boxes are the same as what's shown in this video: My stuffing boxes are shown near the bottom of this album: https://photos.app.goo.gl/TWmyTi1wHuT1g5uF7 I need to take some measurements to confirm, but the Algonac 22964 uses 2-5/8" hose...

My recently purchased 1989 300WE is in storage and while on board getting familiar with things I noticed what seems like an excessive amount of play when I turned the wheel. Of course I couldn't observe the rudders while doing this so I'm going strictly on feel. I would say the looseness is in...

As best I can tell, the rusty mild steel frames attached to the rudder ports are for the purpose of supporting the rudder assembly vertically. Is there an alternate method of doing this? I was thinking of placing a PVC sleeve between the bottom of the tiller arm and a SS washer sitting on top of...

I'm looking at a freshwater 1989 300 Weekender with Mercruiser 5.7 inboard straight drives. It appears to be a very original unmolested boat. Are there any problem areas that I should be looking at for rot, delamination, etc.? Can anyone tell me the brand and model number of the transmissions...
