Hi- I have 4 extra tilt rams for my Mercruiser III (BIG unit). These were last sold in 1972. Two of the rams will move, but very sticky and stiff. I can't find any rebuild kits, but it looks like it is mostly O-rings that would need to be replaced. Anyone have info or remember how to do...
Hi- I have a spare transom unit, including a gimbal ring for my 1972 Mercruiser III outdrive. The ring on my boat is cracked, and I will replace next time the boat is out of the water.
My spare is structurally sound, with plenty of material (and for those familiar with this VERY LARGE unit...
Hi- from other posts you may know I am rebuilding much of my 1973 Cruise-a-Home engine- a Mercruiser 325 (a big block 427 Chevy). So this might be silly, but...
I pulled the pump that draws the river water to the cooling system and cleaned and inspected it. Much of the paint just "flaked off"...
Hi- engine is Mercruiser 325 (basically a big block 427 chevy) in a '73 Cruise-a-Home. Raw water cooled, running in fresh water now, but a history of being in salt water.
The heads are off and at the shop for a valve job. Looking at the short block, and cleaning it up for re-assembly, I...
Hi- In warm California, we don't need to drain for the winter. But, I'm pulling the heads to replace gaskets and need to get the water out of the block. I can't find the drain plug (plugs??) on this 1973 Mercruiser 325 (basically a 427 GM truck engine).
Thanks!

Hello all- My old Cruise-a-Home has a Mercruiser 325 engine with III outdrive. The ignition system is a Thunderbolt, with no other designation. I think it might be the original TBolt series.
The upper station Tach is toast. I have heard and read that this ignition system needs a special...
Hi- Engine is a Mercruiser 325 (427 big block GM) in a 1973 Cruise-a-Home. I am going to remove the exhaust manifold (and risers), intake manifold, and then the heads. Engine will stay in the boat, and there is plenty of room to work. The goal is to replace all gaskets.
From two local very...
Hi- Engine is a Mercruiser 325 (big block chevy 427 ci from about 1972). I'm about to pull the manifolds and risers. They look OK externally, but who knows what I'll find.
I was given a good set of Crusader manifolds for a BBC. Assuming I can do the approriate "plumbing" to connect to raw...
Hi- I'm pulling the heads on my 1973 Mercruiser 325 (it is a GM big block 427 engine). The engine is in a 1973 Cruise-a-Home houseboat, attached to a Mercruiser III I/O. The head gaskets are leaking (but not into the oil yet), and it will be an opportunity to clean things up. I will be doing...
Hi All- I picked up a distributor, with ignition module and what I think is an "anti-knock" module, from a 1996 454 MARK V motor. I would like to install it on my 1972 Mercruiser 325 (427 engine with Thunderbolt 1 ignition system). It looks pretty staight forward in terms of mechanics and...
Hi- This another question that relates to my topic below- "Two station Tachometer issues".
I went to buy a replacement tach this morning because of a HUGE closeout at the West Marine "surplus" store in Oakland. (I got a new $104 tach for $15).
Anyway, the instructions on some of the tachs I...
Hello all- I have a '73 Cruise-a-home with a Mercruiser III with Mercruiser 325 engine. It has a Thunderbolt ignition system.
The tach at the downstairs helm station works fine. The tach on the fly bridge doesn't work at all. There are switches near the tachs, both top and bottom, that seem...
Hi- I picked up a used Mercruiser III unit "just in case" as a spare for the one on my 1973 Cruise-a-Home. The unit is sitting in my driveway, appears in good shape (no corrosion on cases, turns free and easy, reportedly from a boat that burned and has been sitting dry for 20 years).
It was...
This will prove what a newbie I am-
I am looking at picking up a spare leg for my '72 Mercruiser III. When the U-joint is turned (say clockwise), the prop shaft turns the opposite direction (viewed from the the front). Does this make this a RH or LH drive? Stock 427 engine, and my boat uses...
Hello All- This is a somewhat theorical question, but...<br /><br />My new-to-me 1972 Cruise-a-Home houseboat has a Mercruiser 325, seperate forward/reverse transmission, and a Merc III (not Bravo III) I/O. Things are working OK right now, but this engine and I/O were not well taken care of by...
