Craig - congrats man it sounds and looks awesome  8)

Grinder - where did you find that alt bracket and what's it cost? Like Craig said, the one he used (and I plan on using) ain't cheap.

This is where I found it.

This should work as long as it is a Mercruiser/Mando type alternator?

You obviously  did more research then I did. That's a good deal. As long as the existing lower tension mount will would with it. The one I bought came with a new one.

That's what I was thinking too - Craig, does/did your new tension bracket have the same specs/measurements as the one that came with your new alternator bracket?

Thanks again for the help bud...

I'd think it would have to, or the belts wouldn't line up.

I think your right, if they didn't the belts won't line up. I didn't compare the old to the new. I just put all on and it works great. I was able to keep the old belt and use it.

Makes sense to me...time to place an order.

Too bad it's going to be in the 30's and snowing this week, otherwise I might have been able to get this whole thing started! MN rules  :'(

Thought I would post a before and after picture of the engine compartment. The new manifolds makes it seem like there is a lot more room. I know it will be easier to change my spark plugs. :) Overall I am vary pleased on the project and how everything turned out. I was able to keep the cost pretty low. I got great deals by keep my eye on Craigslist and Ebay.  ;D

The exhaust and bilge may be done. But I still have the hatch to put back on. I have put new latches on the hatch, which will work great once I make mounts for on the boat itself. ( Burnin Daylight I think you know what I mean.) In addition to the new latches when I put the hatch on I will install gas struts to hold it up when opened.

Burnin Daylight, I just now saw that post on the national site about you buying the same latches and them not working because of the angle. ( sorry I never responded, I'm hardly on that site anymore. No one over there seems interested in what I'm doing to my boat...)
Anyhow, I am taking care of your problem of having only one screw! Next week hopefully I will have new screws made up and ready to be sold. They will be just like the originals! only with out the slot on the top.

Thanks Shrom.  Everything you've done looks great.  You seem to have gained space in your engine compartment and I lost some.  I'm sure those latches that I bought will come in handy somewhere they just were wrong for my purposes.  I am already starting to get the additonal hardware to be able to mount the latch screws as soon as I get them. Thanks again.  Great job on the exhaust, keep those exhaust baffles in place for sure now.

 You may have lost space, but gained a lot more power in place...

I saw the thread about what happened to you boat. :-/ and when you said about keeping the exhaust baffles in place on my thread, a question came to mind. Does you exhuast not have internal flappers? I know that they are plenty out of the water, but i would have thought they would anyway. Mine do in the tips. I thought about putting those external flappers on as well. Not sure I need it. plus I don't really care for the looks of them. I hope your able to get you back on the water asap! good luck to you! And thank you for the compliments. ;D  P.S. I would love to have pictures of you boat emailed to me with the new Hatch screws on. I can use it as advertizing.

Ordered a electronic conversion kit for my distributor and new coil, Will probably end up replaces the wires too while I'm at it. I have heard these kits work great. Being on the water I believe it to be a good move. Wont have to worry about my points anymore. I am anxious to see what kinda of power gains I get with the 4brrl car, exhaust, this kit and coil/wires. I ran top speed last year at 55mph. with a 19 pitch prop. Any higher prop I lost my rpms. I hope I can run a higher prop now. ;D

I am definately going to do the electronic ignition swap at some point too. Was it easy?
Maybe a new coil. Where did you get your kit from? I see them for about 115.00
I have a Mallory distributor.

I did not receive it in the mail yet. It will be coming Friday. So i will install it next weekend.http://www.cpperformance.com/p-14217-electronic-conversion-for-most-mallory-v-8-distributors.aspx this is the site that I ended up getting the kit and coil from. I think there are other kits out there that are cheaper, but I was told that this is a good kit?  ??? I'll find out I guess.

yes, CP performance was where I was looking at them too. Seems reasonable.

Guys, I need info. or pictures on how yours may be setup. I put the 4 brrl carb on and have questions on how the choke works. It looks like there is a vaccum port on the front of the carb. Do I run a line from that to the intake? or just plug it? or what? I wish I had a better picture, maybe I will snap one this week to put up. It seems to idle and run fine the way it is. ??? Any help would be great. The orange  arrow is pointing at the plunger, I think it might go to? The red is the port I am talking about.

Craig

The vent coming off the front of the carb on my set up goes to the top of the fuel pump.

The choke system looks like a electric choke to me.

maybe Rich will chime in on this one.

Looks great keep up the good work

Darn, beat me to it!  ;D
Yes, there's supposed to be a clear yellow hose from the mechanical fuel pump to that barbed fitting on the carb. It's a fuel pump failure indicator, in the event of a rupture of the pump diaphragm then fuel will appear in that hose and if the leak is bad enough the fuel will drown the carb. See my pic below:



There should also be a short hose going from the base of the carburetor to the vacuum pull-off on the side of the carb. That's to kick open the choke a quarter inch when the engine starts. The choke should open the rest of the way as the engine warms up.

Thanks guys! That helps me out. I will be working more on my boat this weekend. That was one of the things I wanted try and solve/hookup. and now I can! Weather is not quite warm enough to go out yet here but my plans this weekend is to get the engine aligned, outdrive on, hook up that line to the carb. And put the new electronic distributed kit on. Basically I want to have it ready this weekend to be able to go out on the water when i get a nice day.

Hey Shrom gotta question for ya. Looking at one of your earlier pics it looks like you're missing the choke thermostat and link that goes in the spot I indicated on the pic. It's the device that opens the choke fully as the engine warms up. It's basically a bi-metal coil in a small metal housing and it's supposed to have a metal link rod with it to connect to the choke lever on the carb.

See the link below, part numbers 29 thru 33

..... ( sorry I never responded, I'm hardly on that site anymore. No one over there seems interested in what I'm doing to my boat...)...'

Had to take the bait on that one.  I'm genuinely interested in your project, and I am confident others on the other forum would be as well :).  Incidentally, the forum 'over there' is picking up these days quite well.  I like to think these forums compliment each other, not compete with one another.

Can't wait to see pics & video of your boat on the water again.... sure sounds nice on land, that's for sure.
