Default Right size engine for a 33 Egg Harbor

I'm looking at a few older Egg's and notice that they are all powered differently. Does anyone have experience with the proper size of the enginee in this model???

Thanks

Joe

I've seen that boat with engines as small as 318 Chryslers. Saw a 1972 last week and those 318's seemed to run pretty good.
If you are planning on some long distance boating and lots and lots of hours, yes, you should look at diesels, but 3208 Cats is a lot of engine for a 33 footer. I see that engine in a lot of 38-45 footers.
If you are like most boaters putting 50-100 hours a year on a boat, diesels will never pay for themselves. You can buy a whole lot of gas for the money you will spend buying diesel engines.
A good pair of 454's will push that boat along pretty well.

What's the displacement, 14000#? If looking for the less expensive repower, wouldn't an 8.1 ltr gas engine have enough torque and hp to move it along nicely. Probably more effecient than the original power with a lot more ooomph.

Like Chuck said, with diesels, you gotta put the hours in to start getting the premium pay back on the fuel savings.

Chuck thanks ofr your input. I'm really struggling with this. I have 3 that I'm looking at. One has the 318's, one has the 3208 CATS and the one that is in the best shape has 270 crusaders.

Im worried that the Crusaders are not enough for that size boat.

Any thoughts?

Joe

Check out the egg harbor owners website. There is a section there where owners report their engine size, proping, trans and speed to give you an idea; as well as a lot of other information. Note that you need to be very specific on the year. Egg harbors were changing hull designes often during the switch from wood to fiberglass(and company ownership changes). Some of the earliest fg ones were made in "borrowed" molds. Hard vs soft chines will make a difference on the speed/engine ability.

A close friend of mine has a 81' 33 that was repowered with 3116's. They were shoehorned in there and ultimately he needed to raise the salon floor to get the proper clearances. I'm not sure if the 3208's are original so you may want to pay particular attention to how they were installed and the clearances around them for maintenance. I believe most 33's in the late 70's/early 80's came originally equiped with the 318.

Also, what's the power rating on the 3208's...broke a stringer loose with the 3116's

I have a 1978 33' Egg with Perkins 185 HP diesels. The engine are fresh but WOT is still only 14-15 kts. I have fully loaded down the boat with genset, additional water tanks, 200' of chain, inverter, 10 batteries (starting, house, & inverter), and a fully enclosed eisenglass bridge. The boat is well equiped but slow. Email me at kapdan@cox.net if you have any specific questions that I may be able to answer.

I spent a lot of time as a crew member on a late 70's Egg 30'er with twin 318's. Very, very slowwwwww boat. Yes they made a lot of Egg 33's with 318's, but if intend to make long runs to fish, you better go bigger. Now if you are just going to cruise and use the boat for overnighting in a slip, the 318's would be OK. Also, have it surveyed. Many had problems with rotting wood. But they are tanks, with great woodwork and craftmanship in both the cabin and teak decks.

You say one has Crusader 270's. I'm betting that is a 350 (5.7) with 270 hp. I would think that boat with 350's in it would be one sweet running boat. Now if the one with 3208's is at the right price....certainly worth looking at.

I wouldn't consider small blocks in a boat that size.
Big blocks would probably be OK, but she'd still be slow.
I recently purchased a 39' with 3208's- they have a solid reputation for reliability, but as with all diesels (I'm learning) maintenance is the key- take care of them and they'll take care of you. If not, the repair bills can be HUGE- I overheated one motor badly (hose clamp that split) and the mechanic told me it would cost close to 20K to rebuild it (fortunately I didn't need it).
Out of the three you mentioned, the CATS would be my choice because the small blocks will leave her underpowered. What is the HP on the CATS? Mine are 355 hp, but most popular were those rated at 375. I think they were available up to 425 hp, but the higher the output the shorter the time between overhauls.
If you have the coin for the diesels, they have reasonable hours and they pass survey they'd be a good choice.
If you can find one that's recently been repowered with HO big blocks it would be an interesting exercise...

Also, keep in mind that the CAT boat will burn approx. half the fuel and have twice the range of the gasser. Good luck

With gas motors at current fuel prices, the boat will cost you $93.50 per hour to run assuming 18-20 kts at $3.50 per gallon gas....With diesels you are looking at $33.00 per hour assuming 20-22 kts at $2.50 per gallon....That would be a savings of $9000.00 bucks a year assuming 150 hours of use. Now assume you will have the boat 7-10 years and your overall savings would be $63,000.00 to $90,000.00...After 10 years your gas motors will be need to be rebuilt or replaced while your diesels would be at about 25% of their expected life span. Both will require lots of expensive maintenance, however, no tune-ups on the diesels... Figure in that resale on your diesel Egg would be 25-50 percent higher with a diesel power package.......how are diesels a bad idea????

offshorebri,
I don't dispute your figures, but I know very few people that put 150 hours a year on a boat. I probably know more people who put less than 25 hours a year on a boat than people who go 100 hours.
I agree that some diesels will go many thousands of hours in their lifetime but I also believe that a lot of these high powered, turboed diesels don't last that much longer than a well maintained gas engine.

All good points on gas vs. diesels. JOE D NJ really does need to give more info on his intended usage. I guessing the NJ in his ID means he does his boating in the Garden State. If he is using the boat for offshore fishing, and intends to make regular runs to the canyons, then he will rack up 100 hours in no time. If cruising and live aboard is his passion, then gas may make more sense.

For sure.............I used my boat maybe 20 times this year with the weather and work issues and put 140 hours so far........A day canyon trip in July consisted of starting up the Yanmars at 3:30 Am and shutting them down 15 hours later back at the dock..... If you boating consists mostly of afternoons in "Cocktail Cove" then take the cheap way out........Good Luck trying to sell a 30 year old gas powered EGG HARBOR though.....

Actually, I had a 1971 WOOD Egg Harbor with twin 460 Chryslers in it that I sold 4 years ago without any real problems selling. The boat is still in the same slip I had it in.
There are probably 4-5 wood Eggs at our marina. No, they don't make the run to the canyon but they still have some good years left in them, and serve their owners well for what they want them for.

Displacement on the older Egg 33's is 13K pounds according to the Power Boat Guide.

If you put less than 25 hrs a year on your boat... sell it!

Last time I looked Diesel cost more than gas. Keep in mind that Eggs were notorious for rot around the salon windows and doors, since these remained wood for some time.

aj,
We have a 38 foot aft cabin boat that we spend every weekend on. We don't put lots of hours on it, in fact this year, less than 25. That's 25 hours on the engines. We spent MANY hundreds of hours on the boat.
