Hi everyone,
A while back I posted about my Mercury 850. I blew cyl 2 in my old one and bought a new powerhead from a guy who had his lower unit stolen in the marina yard.
I water tested it on his boat before I bought it, and after a compression check. Compression was good all around and the...
Have a new transom and floor in my boat. I epoxied in the brass tube that sticks through the transom to drain the bilge. The end which was flared is inboard and the straight end is outboard. It sticks out about 1 1/4". I expect that I need to cut it so that there's about 1/4" sticking out...
Does anyone know if floatation foam is legally required in Canada?
I just redid my floor and transom and the boad had zero foam in it. Additionally, there's really no place to put it. It's a small boat, so maybe it's under the size were foam is required?
Anyone know about this? I don't mind...
I'm about to refasten my deck/hull and I have rivets and washers. I have the largest rivets I can get without a special riveting tool. The boat has been taken apart before and the lip of the deck and hull are full of holes. I'd like to use the same holes that I drilled the rivets out of, but...
I did a search for rivtes, rivet, reattach, rivet deck... I found a few interesting posts but none specific enough.<br /><br />You'll see my project in my signature.<br /><br />The deck has been removed before. There are a lot of rivet holes. I expect that what was done, the first time the...
I've been looking to buy supplies to do transom and stringers in my boat.<br /><br />It's a 15 thundercraft wildcat (looks like a small checkmate) with a Mercury 850, straight four cylinder 85hp outboard on the back.<br />It's a small boat used for pleasure touring at speed, and water skiing on...
West system says that the epoxy will reach a "green state" or Gel state after pot life but before final cure. It says that you can reapply once it's in this state and it will chemically bond with the first coat. The longer into the gel state the less effective the chemical bond will be. <br...
I have a 15' thundercraft wildcat. The transom is roten and so I expect that the stringers are rotten as well. I saw ants on it when I untarped it this spring as well, so that worries me.<br /><br />I have a week of vacation to do the work. I have one bay of a two car garage to work in if it...
I finally found a powerhead for my motor and that's just about put to bed. I now have to address the spongy spots in my transom around the bolt holes. I've been reading all the transom/stringer questions I can search out here and still have questions of course.<br /><br />1. I plan on...
1973 merc 850 with tilt and trim.<br /><br />The tilt currently works entirely and will hold the motor up. The trim leaks down under power.<br /><br />I was wondering if this is any indication that the problem is in the cylinders or check valves in the pump.<br /><br />Most of what I read in...
I've been wrapped up in rebuilding my 850. I found a powerhead in working condition which is a better option than boring.<br /><br />Can anyone suggest pricing?<br /><br />it's a 1973 merc 850 thunderbolt. No lower unit (just mounts and the drive shaft housing)<br /><br />I'm Canadian, so it...
I have a mercury 850 7033755 I think it's a 1974.<br /><br />I'm in the middle of a rebuild and my connecting rods don't look so good. They're CAN$180 each so I don't want to replace all four. I think I nicked one pushing out the wrist pin.<br /><br />The manual says nothing about replacing...
I'm just about to buy pistons to have my block bored after damage to cyl. 2.<br /><br />I'm told that I need to check the journals on the crankshaft for round. I'm also told if it's out by more than half a thousandth that I should consider the scrapping the project. I'm a little concerned...
I've posted various questions before about rebuilding my mercury 850 serial no 7033755. I am currently at the crux of the rebuild, just before spending a great deal of money and would like some popular opinions about my options.<br /><br />The initial symptom was no compression in cylinder no...
I'm going to be honing the cylinders of my Merc 850 with a deglazing tool designed to be used with a hand drill.<br /><br />Is there an alternative I can use to honing oil? It is rather difficult to find and the machine shops I've called don't sell it and aren't intersted in giving or selling...
