4588 Pilothouse Engine Replacement-gctid816133

[Guest]

Has anyone replaced their engines in a 4588 Pilothouse? I recently purchased this boat and would like to refurbish from the ground up starting with the engines.

If you have, did you buy remanufactured engines or did you have the original engines rebuilt. Would also like to get an idea of cost.

Perhaps start with the best and find out about your rebuilds....

We re-powered our 4788 in 2011/2012

We used Cummins Reman engines. The cost of the 330 HP units was then approx $20K per engine.

We thought about the same engine in a smaller size like 210/220 hp for longevity reasons, but decided on the 330's in the end.

The smaller engines only would have saved about $3K per engine.

In your case you would need new transmissions as well.

Installation is another issue. Figure another $20K for the installation. Some will scoff at that, but believe me that at close to $100 an hour, your costs will add up quick.

I've never done a marine engine but I can't imagine how it would take close to 200 hours to replace two engines. I know it's a big job for sure but 200 hours..

Kevin - when you did yours did you go through and service/replace/upgrade everything you could while you had access? I'm talking about battery wiring, holding tank, charger mounted on inside of port hull etc. etc.. then paint everything?

Sorry...one more thought. I know it's exciting to get a new boat and want to make everything perfect...I did my own version of that too. Two years later and MANY MANY boat units later I've finally slowed down. Is there anything currently wrong with the engines that would warrant replacement? Why not go through them and get them tuned, replace all the hoses, thermostat, water pump etc. Refresh them accordingly? There's going to be many other projects that are going to require not only money but copious amounts of time! Example, davit system, window seals, ALL exterior calking, windshield seals, electronics, galley upgrades/modifications...those are just a couple key areas. Congrats on the new boat...I remember very clearly getting ours..it's super exciting! Welcome to the best place on earth for information on your boat too!

Simonsen asks a good question - why replace rather than rebuild? As ksanders confirms - you would need new trannys. Then what about props, sending units, gauges, etc. The $20K install seems about right.

Check out the engine replacement section of my book: Fuelish Pleasure Boats. Amazon has it and I think they left it open. It's free to look inside and you might be able to get to the section that has the list of numerous items that a boater might need to replace if a complete repower is involved. It can be a LOT more complicated than you think.

With the design of the hinos why replace the entire engine? The cylinders are not cast into the block and can be individually be replaced, the head can be refurbished and everything else can be cleaned up and rebuilt or refurbished as required.

I repowered my last boat and the ratio of power packages to everything else is about right, and I did all my own work. I replaced rather than rebuild because the rebuilt was going to be close in cost to the all new was a push and I had a bad experience history with that design.

You could still pull the engines off their beds up into the salon O'Neal a time, and do the work you want with each one out of the way.

Just my thinking.

Bugaboo, think this over carefully, very carefully. The cost to refurbish "from the ground up, including engines" will be mega expensive. You could EASILY spend 150K or more on a project like this. Suddenly you're into a 1987 ish boat for a ton of $$$!! It might work for you if you plan to keep that 30 year old boat for a long time as that's the only way you'll realize the value. Once the project is complete and the mega money is spent if you encounter any unexpected life event, family illness, injury, economic downturn, etc., that forces a sale you may be forced to take a substantial loss.

Thank You everyone for your input. I agree, replacement cost to high for the age of the boat. Rebuild and replace parts as needed seems to be a better chose. I'll do some research on it.

I'm probably going to do as much as the work on it as I can. Would really like to focus on the power plants and all mechanicals first and then focus on the cosmetics .

It's not like you are R&Ring the engines and putting in the same thing. Lots of labor involved in figuring out the "little" things. All billable hours.

Think about the exaust, the cans, the hoses, etc... Just figuring tat out, then doing it is labor hours. Re-routing the seawater system to work, more hours. Then there is the instruments... More hours. Easy 200 billable hours. Just the big labor the removal and re-install of the engines is minimum 3 guys, really 4 for two to three days. Thats minimim 60 bllable hours right there. The new engines won't just bolt up. There are engine mounts to figure out, parts to fabricate. This is a HUGE job.

Yes, it takes 4 guys, I saw them do it in my 4788. Two fork lifts with long booms, and two guys in the engine room. One fork lift in through the port window (which you have billable hours to remove and re-install), and one through the salon door (which you pay to remove and reinstall)

Yes I had lots of stuff done. It adds up quick. My re-power and re-furb ran $140,000.

I have a friend who did a 1980's Norland from Gas to C series Cummins engines. His cost around the same and all he did was the engines and Gen.

You should be able to completely overhaul that engine while it is in place.

What do you think these engines really need? They (EH700) are incredibly robust and may need much less than you think. Do you have symptoms or problems you can articulate?

Hello Smitty,

I purchased the boat at auction. her Port Side engine over heated at sometime and needs to be rebuilt. Oil pans on both Starboard and Port are rusted pretty badly.

Looking to have her for a while and would like to make her right. Spoke to a machine shop today that would rebuild the engines (not an easy find). I need to get back to them with serial number

for an estimate (or ball park) to rebuild or replace.

Bugaboo, where's your home port? Knowing that may help us guide you to some resources local to you. Something else you should realize is new or rebuilt is not a guarantee that you will be trouble free. Or even trouble reduced. Certainly changing the risers to stainless and have the manicoolers and bundles serviced, maybe have the manicoolers powder coated, rebuild the water pumps, replace the hoses and clamps, have the injectors serviced and maybe, maybe have the lift pump gone through. You may want to change out the coupler plate, talk to Mike at Harbor Marine in Everett, WA, possibly the most knowledgeable guy around about that and Hurth transmissions. But, were it me, I'd bank the rest of the estimate for the rebuild for an emergency.
