Repower 5.0 liter to 5.7 383 stroker

[Nehalennia]

The engine install is starting today. It is a fine looking engine

Jim

Hopefully you're adding fresh water(closed) cooling to it also? It would be a shame to start it's life subject to salt corrosion.
It's sharp for sure.
Best of luck.

+1 on this. If it were me I'd add a full (block and manifold) closed cooling system before I dropped it in.

Who makes a full block and manifold closed system for this engine ? All the systems I have found still allow sea water into the cooling manifolds. This boat is dry rack stored and gets flushed after every use.

I have a San Juan engineering "full system" on my 350 (5.7EFI). It has been great. I really encourage you to install one, wether it's San Juan, SeaKamp or Mercs.

Thanks for the info, how long has your system been installed? Obviously sea water still comes in to cool the engine in some sort of heat exchanger. Can you give me a brief explanation of how it works?

On a "full" system the sea water goes through a heat exchanger then out the elbows. The manifold and block are cooled with "fresh water" which is actualy antifreeze just like you use in a car or truck.
On a "half" system the sea water goes through the heat exchanger then to the manifolds. Only the block is cooled by the antifreeze.

Westie explains it well. Definitely get the "full" system for your sparking new engine. I run a hydronic heater off mine too, which in FL you most likely won't need.

Whatever you do, DON'T!!! run seawater through the engine before getting your cooling kit. Keep it a saltwater-free virgin.

What pitch do you currently have?

I have 20P currently.

 

[jimandsue60]

I just spoke with San Juan Engineering, they do not offer a "Complete/Full" system for this engine. My only other option would be a complete/full system from mercury. Unfortunately this system would require a new ecm to the tune of 2500 $ plus. The engine is going to be installed as is with out any FWC systems.

Good for you! You haven't lived until you boat in saltwater with no boundaries. Let her eat and just do the normal maintanence and you'll be fine.

I'm curious what your gear ratio on your drive is now. I run 26s

I'm curious who you spoke to at what phone#. Call and ask for Brad (360) 734-1910 . Make sure you tell them exactly what engine you have. I'm not sure what you just spent on your new engine, but I'm sure it was over $6k. Adding a FWC system will ensure you get it's full value and life out of it. My "FULL" SJE Kit was $1500(that was a few years ago. I think it's a huge mistake to not add FWC, but it sounds like you made your decision. Best of luck.

I disagree with this advice. Why wouldn't you want him to protect his engine and performance completely>? Even a 1/2 system will protect the engine.

I'm not trying to talk him out of it, he simply stated what he was going to do. I only know saltwater boating (26 years worth of boat ownership) and I always find it funny when people bash on saltwater boats. Yes the saltwater can play havoc on your equipment but if properly maintaned then it will last for years to come. Me personally I would rather have no limits to where I can go (via saltwater) than to be stuck in my travels (but your boat may last longer). Just saying?

"I thought my mind was made up but maybe not. I thought I had spoke with San Juan Engineering but actually spoke to one of their distributers at gotomarine. I just left a msg for Brad at San Juan. My engine with install is well over 12 thousand dollars, not to mention 2500 plus to replace the corroded out transom bracket which was found when the engine was removed. It all adds up! I guess I am a great candidate for the Hole in the water club.

Thanks

Yea but Sanibel is a beautiful place to boat and well worth the money :thumbsup:

I just believe adding FWC "IS" part of the properly maintaining the engine. I absolutley agree with you how wonderful boating on Saltwater is. It can't be beat!

Yeah, even more of a point to protect that beautiful piece of iron you own. You can continue the install to not hold up the shop and add the FWC later. I just recommend doing that before you dunk it....even if it's a 1/2 kit.
Again best of luck.

I agree with the salt water portion. I am not so sure I agree with the FWC "IS" part of properly maintaining the engine. My boat is a 2003 with the original engine that was just removed for 3 cylinders with low compression. I only owned the boat for the previous 3 years. It had 2 other owners before I bought it, so I can't say how it was treated. So that engine was in operation for 10 years total. If it would have been maintained as I maintain it now it quite possibly might be running strong. I am putting about 175-200 hours on it a year. If I were to keep that up for the next 10 years that could be close to 2000 hours at which point it would have to come out for an overhaul anyway?

I do realize that I will have to change out the heat exchangers within a few years (without a FWC), is that still necessary with a closed system?

If you don't have FWC you won't have any heat exchangers. You'll just be cooling through the engines cooling jackets with raw water. You will have to replace the exhaust manifolds in 3-5 years as they will also be cooled with raw water vs. coolant.

I'm fairly sure that the question was intended to be "manifolds and risers" and not "heat exchangers." I'm interested in that answer too.

That is correct.

THe best thing to do is use your boat when in saltwater. The more you use it the longer it will last. Letting them sit around for things to corrode is when the trouble start. My last boat had an outboard and was 12 years old with 1600+ hours on it and compression and looks was like brand new. Flush after every use and run the thing, you'll be OK.
