Looks like he had bow thrusters..... Impressive at ant rate.

That's the plan!

This I/O motor has been well cared for and runs beautifully BUT...and there's always a BUT... The engine/ drive was overheating and we could not find the culprit. Many new parts. Will seperate although I will not ship. So, southern Ontario.. come an get'er. no reasonable offer refused. Sean...

Mission accomplished. 4.3L secured (along with everything I need from a donor.)

Well, I went for the whole 9 yards.... Vortec heads, Edelbrock 600cfm 4bbl carb and performer manifold. A mild porting job, 1.6 rockers....and I'm debating a new bumpstick. I'm expecting numbers in the 225 HP range.

Mine is her finding out just exactly HOW MUCH I spend on it!

I got the fever...bad. The 1996+ Vortec high flow heads are now at the shop getting rebult with a little bowl work + some cleanup and 1.6 exhaust valves. Carb and manifold are being shipped. Now I'm looking at 1.6 rockers, a mild cam and still cant decide on the performance exhaust (but I want...

Hey, managed to find a 17' Edson Sunbird GT with a 4.3 / alpha 1 combination....Got it at the right price (with a trailer too). I took it directly to my buds last night, and today it has been stripped bare. Also found some 4.3 Vortec heads for $120 /pr and then orderd an Edelbrock 2114...

Nathan, Usually I'm all for saving ANYTHING. I can't imagine how much I have spent on ressurecting old vehicles. Currently I have 3 snowmobiles from the '70's that i will never ride in my garage under restoration. I did the Donzi last year and I am still working on the Greavette and today I'm...

That's actually pretty funny! Glad everyone is okay....Congrats on the new boat too.

New manifold and riser.... STILL OVERHEATS! That's the sound of the fat lady singing for thid powertrain folks. This motor is coming out and i will be instralling a 4.3/Alpha for next summer.

Update*** The BIG CRUISE event made $11,500 for cancer!!!!! And yes, my boat is still broken. New manifold will be on today. Hope to test tomorrow.

You could consider a classic wooden boat to restore... They can appreciate in value, provide great satisfaction in restoration and also be a super all around family boat you can have a blast in. Plus, they don't have to cost alot and come as outboards too (I have no idea why you guys like...

Hey Eric, Welcome here! I've only been around here a short time but, It's a good place. I'm sure some of the guys will chyme in on you questions. Cheers, Sean

Holy smokes! There is alot of info on this upgrade / swap online.... Looks like Edelbrock makes the carb and manifold. Alot of talk about Vortech heads too. Not sure yet how much of a part they play....

Wow that's it? who'd a thunk just that would net 30HP! Looking at an '88 and an '89. UH oh...looks like most of those upgrade parts are NLA. probably best to hold out for the "real deal". Unless... Does anybody make an aftermarket kit?

I would LOVE the 4.3 MPI @ 220 HP....but I don't need another mortgauge on my house. So, does anyone know how to make a 4.3 175HP in to a 205HP ?

Current 165 HP IL 6 engine/drive weight 715lbs... SBC 260 HP V8 /Alpha = 890 lbs 4.3 205 HP V6 / Alpha = 665lbs.

Not sure if I have the clearance under the hatch for a V8. There might be a weight issue also and more potential issues relocating the fuel tanks if I move to a SBC. I'd LOVE to stuff in an aluminum block V8 but I have not won the lottery yet. My buddy has a similar Greavette with a 4.3 V6 @...

Okay, so with the issues on my old Merc 165 IL6 I am considering a power upgrade to a mercruiser 4.3 V6 / alpha. I have found several "donor" boats that are in decent shape at a decent price however, the majority have the 2bbl 4.3 pushing 175HP. Spending the $$$ for an upgrade I would hope...
