Repower 311-SR1 1989
 

A few weeks ago I posted a threat about frost damage of both 454 MAG Mark IV motors. So they need to be repaired or replaced, most probably covered by insurance but not finalized yet. I am in contact with Teague for a new rotating assembly which would take my existing components.
For you guys it seems kind of silly, but over here everything related to US V8 enigines is rare and expensive, especially knowledge.

Another question is, if I would like to go for a pair of ready drop in motors, which types will fit without rework?
Would this boat take 454 or 502 Mag gen V engines?
I prefer a pair of 502 mag motors but I hear so many different stories in my area about the (im)possibilities.
I am sure many of you know the details.

Thanks for your input

Paul

Just completed a similar project on my 89 311, pulled my 330s and replaced with a set of Gen V 502 mag motors. Used all my stock accys and added electric fuel pumps. I went for a carb setup which is easier for me. I upgraded to Gil exhaust, but my stock exhaust would have worked.

just about any BBC should work ...454 up to 525 EFI ....are you looking for big HP ? 502MPI's or 496's might be a good choice .... Are you saying your checking into "long" Block Assemblies from Teague? that would be block and all internals including heads ...."short" block would not include heads .....m

Well, I am not looking for big power, I would like to stick with the bravo's and I believe that for those drives 420hp is about the upper limit to provide reliable operation right?
That's why for me 502 MAG MPI/carb 415hp would be preferrable.
In this situation I am going to spend quite some money (either insurance or myself) and it would give at least a better feeling if there is also a performance improvement and not to stick with the 2 x 365hp although the boat was running great with those engines.

I have been checking into short-block assemblies from Teague. Disadvantage is that it will still be 2 x 365hp but it might be the best way if insurance is not covering the costs.

I have been checking here at local dealers, but they seem so incredible expensive to me. The offer a CBB 385hp carb for 9000,- euro, that is around $ 11.000,- US.
And they can't tell me any spec. Are those motors als MAG motors, they don't have a clue.

So a good option for me would be a pair of fresh 502 MAG MPI taketouts. I have a business contact in Ford Meyrs who can take care of shipment.

Any advise is welcome.

That is looking impressive, great job. So you are saying that your 502 Gen V fits whithout rework (engine mounts as an example) into your boat?

You won't believe the trouble you have in the Netherlands when is comming down to these kind of things.
What speed does your boat see with this setup?

Hey Paul ......buy my 311 ....600HP ..new drives ...Hydraulic steering .....:)

Sell your boat without motors .....or swap my motors to your boat and sell my boat ......

Paul,

I have a pair of turn key Hp 500's Gen IV blocks, low hours ( less than 100) on freshen up

$ 13,000.00 USD for the pair. These are spare for my 382, currently using SC 600's in the boat

I can send pics & specs if you are interested. Engines are loacted in Virginia near Wasington DC

Now that sounds like a reasonable deal for you Paul.

James - you say Gen IV blocks; how complete are they? Everything included, heads, carbs, etc?

Super nice upgrade Mike. I can't imagine how much cash you poured into that deal!!!! After all that, why sell now?

How much do you want????:drink::drink:

Paul, you are correct that a take out is the best way to go because of all the accessories and bolt on stuff. I just put 2002 500 HP
EFI engines in my 89 311 with no issues. The mounts, exhaust (Stainless Marine for me) and everything else works. I think the Bravos can take 500 hp if you drive it well and don't try to do waterski starts. The problem with getting later generation long or short blocks is that some of your accessories may not match up, and things like the valve covers will not fit.

My Hp 500's can be run on the engine cradle they are kept on, just need a 5 gal can of gas and battery. These are not rust buckets either. The price is right to eliminate haggling. These are kept as my spares for my boat, so they are ready to run

Blocks are 1996 when the boat was new, I think that makes them Gen IV ??

James,

Sure I am interested. Please email me the specs and some pics: [email protected]

Thanks in advance.

Well, if these enigines are 1996, they don't seem gen IV to me, I assume gen V.
Please email me some more info.
As far as shipment goes, it should be possible to arrange a pick-up shipment, alternatively I could contact a business partner in Ford Meyrs to arrange.

Well, that is also very attractive, great boat.
That kind of power in any type of boat is extremely rare over here. One German guy is boating with a Nortec equipped with turbines but I guess he is the only one in europe so far.
It is a pitty it is such a hassle to ship a boat , costs, VAT, import duty and whatvever they can find to charge you.
In this case I would sell my boat without power.
I will also investigate what is involved when shipping a boat to the Netherlands.

35K .... I really hate to part with it ....and I might not ....picking up the 353 this weekend ...If its not everything I think its going to be I'll just Flip the 353 and keep my 311..at least that what I told my wife ....:kiss:

...I'm not telling you anything you dont know but it draws attention everywhere we go ....m

Evidently, you have too much money!!!:drink:

35 is not a bad price for your boat, you should be able to get that. If I were really looking, I'd be on a plane to Fla. right now!! Fact is though, my next boat will be a cruiser. Just can't stand the thought of wallowing around in a big, bulbus tub but I want more room and hang space.

The motor mounts all lined right up, didn't even need a single adjustment.

Does anyone have any experience with engines from PPT, Performance Product Technologies?

Paul

If I would go for the HP500's from James, what implication would that have on the prop's?
I am running the standard prop's which came with the boat, Mirage Plus, 3 blades. My engines were running 5000-5100rpm WOT. I assume something needs to change with the HP500's.
Does anyone have some experience with this combination of boat and power?

I just put HP500 EFI's in my 89 311 and I am banging the rev limiter with 26P Bravo 1 four blades with a full tank and three people. I have a set of 28's I'm gonna try next and see what happens, any luck I may be able to spin 30's, but 28 four blades are probably going to be about right.

I think you'll end up with the 28's ....

Please let me know the results. Testing over here is not really an option, so I need to buy them.

Ted, have you been testing already with the 28p's? I am curious. If they work out well for you I am ready to buy a similar set of props.

Thanks,

Paul

No, I had a real busy weekend but I may get them on this week, my friend that lent them to me is going to have his boat back here some time soon and I need to give them back. I will let you know, we have a poker run this weekend so I may give them a nice long test drive :drink:

Which type of brackets dit you use for the shift-cables and throttle cable?

Thanks for your response.

Paul

I was able to use my stock carb plates for the throttles. I had to order the gil brackets for the shifters. You can also just mount the shift assembly to the transom, cleans up the motor a bit.

Thanks for the info. I got partnumbers of these brackets from Offthefront, very helpfull. I already ordered them.

Finally Spring arrived, the weather is perfect and it can't take too long to get the boat back in the water again.

The HP500's from James found their new home in my 311 last year and they are running perfect.
The end of last season I have been running the old mirage plus 23P props and had to be very gentle on the throttle.
65,5 mph GPS @ 5200rpm and about 75% throttle. Not too long because they will run lean in this way I think.

So, time to swap to another set of props. I have checked into prop test/exchange programs in Europe, I can't find such.
yesterday I came across a good deal on a set of bravo 1 28P, but following what has been posted already is 28P maybe too much.
Maybe someone has new input since I posted this thread and if so, please share your experience.

Thanks
