I was going to let the exhaust heat go through but wanted to contain the engine heat away from it with a separate system. Plus I live really close to the beach and it will see salt water was my main reason for wanting the motor on a closed loop.
So do you think im trying to over complicate it...
Its a new block and heads. I'm building the kit. I'm trying to eliminate extra heat from going through the out drive. I've read that through hull exhaust boats have a longer life on their out drive due to reduced heat but I like it quiet and thought ide lose some heat elsewhere. Maybe I'm over...
I recently got a 76 220 ov it has a 302 and a alpha 1 out drive.
I'm one of those people who like to modify things to make them last as long as possible. I am converting the engine to a closed loop so I can run antifreeze with a heat exchanger. I want the water from the out drive to cool the...
Lol no it is a marine 302 I'm replacing the old 302 with. I'm being told go gm. I know the difference there are many all the way down to the pistons.
My question was the mounting of the gm motor. I tried to specify that I'm not asking about the block or comp on its just putting it in. If I...
Thanks but that was of no help I'm a master mechanic and I'm aware of the specialized marine parts for safety lol Not to be rude but please read the questions. in my question I stated that I'm aware of the marine bolt ons like starter at ect... And simply wanted to know how to adapt everything...
Thanks. I would convert this one its the same block and heads they use just need the bolt ons. It also has ARP head and main studs as well as a girdle kit to strengthen the bottom end.
I am unsure of the current water line but this will be a project for later. I already have a new 302 so...
OK thanks. I have searched and most are incomplete partial videos. I was hoping someone on here who has done it would chime in. But I'll continue looking and post my findings
I'm very familiar with Peninsular and already have a 6.5 its an updated amg block and heads. I am aware of what all I need just wondering how a slower turning torque motor would do. I know the gears would be different but what drive? Bravo?
Looked up the weights and I would be adding at least...
I was just wondering if anyone has a gm 6.5 or amg 6.5 or even the 6.2. If so how does it perform? What out drive do you have or recommend. Thinking about this for a 220 overnighter.
I just bought a 78 220 powered by a 188 and a alpha 1 drive. I'm being advised to go gm that the 188 won't push this very well. I don't see this being fast anyways and don't want a gas hog.
How do y'all like this engine?
It doesn't seem cost effective to swap I already have everything ford...
I'm not wanting a ton of power and though I like Chevy better and its more popular these days in boating. I just can't see myself tossing all the ford stuff in the trash. A 302 is a great Lil motor and I figure 220hp or so will move it just fine. On a larger boat like this I would think more...
Thanks for the advice and your right I will proceed with the project lol. I have 3 kids and the older 2 are wanting a project they can do with me.
I'm looking at it basically like an empty hull. what does look good just the age makes me wanna replace it while I'm that deep. I got the boat for...
What about the exhaust heat going through the drive. Is it a lot better to run it through the hull?
I know water goes through the manifolds and then through the out drive with the exhaust.
could I get an auxiliary pump and push fresh cold water through also to counteract it. Haven't read of...
OK did some more research and it is a alpha 1. Not the gen 2. Anyone know what kind of power they will take? I know off the line punching it will break them but just normal cruising what will hold up? I plan to build the 188 and put back. Not a lot more power but I have a block with a steel...
