Hello All,
Been a while since I was on here last. Redfury and a couple of others will probably remember me. Sorry it's been so long. Here's the update & recap.
18' Lasvegas Sahara Tri-Hull with rotten floor, saturated floatation foam, one rotten cross member. Stringers looked fine although I...
I posted a few questions a yr ago about my Thunderbolt Mercury 80 HP outboard. A great guy answered the questions and referred me to a friend of his who lived in the Shelton Washington area who has about 50 yrs experience working on them. I lost all my computer data when my system hard drives...
I am going to be replacing the gauges on my boat. I currently have the regular run of the mill - speed, tach and battery. My motor is a 1969 Mercury Thunderbolt 800. I plan on putting in the Sierra model gauges. Besides the ones listed before, are there any suggestions? IE: water pressure...
I have a 1969 Mercury Thunderbolt 800. Serial Number: 2668954. I have gone to oldmercs.com and to mercruiserparts.com but have run into a few snags. I have no fuel getting to my spark plugs and think this has to do with the carbs. They have fuel and there is fuel in the fuel filter. I think...
I ordered the maintenance manual for this engine and have received it. Upon going thru the manual though, I found that it does not really have an IPB (Illustrated Parts Breakdown). There are parts that I would like to replace on this motor but without part numbers I wont be able to do that...
Here is a question for those that have rebuilt a mercury engine and have used the service manuals. I am looking at getting one of the following manuals, and would like to know which is the better manual for my particular engine.
A - Seloc All 3 and 4 cylinder models 1965 thru 1989 $30.95...
I would like to know from all those that have done this before, if it is ok to put an internal gas tank in here or not. I would not be able to install all the foam that I would like to in that area but I can put it in other places hopefully. I have attached a pic for your discussion and...
Does anyone have a service manual for a 1969 Mercury Thunderbolt 800 or access to one? I have some questions dealing with mine. I can't seem to find a part number for the fuel line that goes from the inlet to the fuel splitter for the 1st and 2nd carb's. Plus all the screw's, hardware and...
I have a 1969 Mercury Thunderbolt 800 2 stroke. I was told that this engine is primarily supposed to be used in fresh water. It was not intended for salt water use. As such, it will go to pot quickly and basicly self destruct then my only option will be to replace it with a new engine. A few...

Q1: I pulled the foam out of the bottom of the boat with the exception of the front part. I do have a question for replacing it though. When I go to put it back in, if I sprayed it or coated it with something like epoxy so that it would be sealed and would not absorb any water that might leak...

This engine needs a new prop. The only number on it is:
48 77344 A40 17P
I know what the 17P stands for but not the rest. I have done a search for this prop and it comes up blank. I do not have the manual for this engine so I do not know what the manufacture recommends as top rpm ect...
As you can see by the pics, the floor is cracked and broken in a few places. There are multiple soft spots all over it. I am not sure where to start or how to start in fixing this. I have order'd three books on fiberglass repairs and boat repair. I'm waiting for them to come in. I order'd...
I have been looking at keelshield for the keel of my 20' tri-hull boat. I bought it a couple of weeks ago and want to fix it up to make it look great again. The people who owned it before me, beached it quite a bit by the looks, (I'll post pics tomorrow 17Aug) or they could have hit the trailer...
