I agree with the rest of the post though. You're better off with the 350 than the 305.

None of the differences are critical, if you don't use the

you want the sturdier components.

350 to 305? Didn't you notice you're going the wrong

economy. I'll give you one guess what you *will* notice,

FWIW, the "targetmaster" is the el cheapo GM replacement. I

Agreed. I have a 305 in my '77 Marquis. It's turning into a nice boat, that is, when i get the interior finished. But if I have problems with the stock 305, I'll put a 350 in it's place. A lot better power per fuel usage.

Well Rich, this is a boating group isn't it? I Especially this year, when I'm gonna start working on finishing my boat and planning trips I'm doing a lot of research. And I find old threads that have some good advice. People who never post in here do the same. That's how I got onto rec.boats many years ago, by doing a google search on a boating question. So, that's what I do.

BTW- I made up my mind that I won't be evolved with political/religious threads any more.

I am not sure I want to keep rubber parts below the water line on a

boat that stays in the water around here.

Hey, these ancient posts have a wealth of info. and I'm enjoying them .

Greg, I could switch over to outboards, I've had a few of those too.

The antique outboard site is still alive and well:

http://www.aomci.org/

I still have a place in my heart for a mid 1950s Evinrude Lightwin or
Ducktwin.

Here's a page on reviving a long out of service outboard:

The 350 did a good job of pushing that 21' Proline across the water! My SIL had a v6 in his
Chapparal 24'er, and it pushed that boat nicely also. Might be something to consider if you don't
need a lot of speed.

That's an absolutely SPECTACULAR idea!

I think you should also consider finishing and planning trips on those two Moto Guzzis of yours!
And, if you want to talk about them, that would be great also!

The big question is whether I should hang the Winchester

or get one of these to hang in the trailer.

The GM v-6 is a great and durable engine, that packs a good punch with 'reasonable' economy. the bad part about swapping from a small-block to the v-8 is that the exhaust manifolds are different, (for obvious reasons), where small v8's would likely interchange.

Plus, small v's are in plentiful supply.

Otherwise...

Now that the 4 strokes are getting better, there is very little

advantage to an I/O.

My mother's family all ran "Bay Built" work boats with inboards and I

thought an I/O was the best of both worlds until I got down here.

The ones I was familiar with on the Chesapeake were still trailer

boats. Down here the only I/Os you see are "go fasts" with big block

V-8s that seldom get wet.

I know exactly what you're saying Greg. But unless you have a sail boat, and like to pay slip rents, around here, trailer boating rules. Mercruiser alpha 1's are easy to come by due to long term use. I mean' it's kinda hard to improve a hammer.

And I/0 engines are something that most parts you can get through NAPA. Like carb kits, solenoids, belts etc. I wouldn't use an automotive water pump, though...
