Hi,

I have a couple of questions about a PCM Excalibur 330,i want it to put in a BFN.

-where do i find/ get a service manual?
-What kind of Gauges can i use analog or digital?
-what kind of wiring harness do i need from the engine to the dash?
-and wich prop do i need?

The engine is a PCM 330 Excalibur from 2003 with a pcm 1.23 trans. The wiring harness connection on the engine looks the same as mercruiser (10 pin). I want to to use the original gauges of the barefoot nautique from VDO.

All advise welcome!

I know it's possible from talking to SKIDIM about it, supposedly not terribly difficult. I would talk to Jody at Florida inboards, he does a fair amount of motor swaps.

There's a guy on this site that put an Excalibur 330 in an 80s ski nautique as part of his complete rebuild. I'd imagine some of the principles are the same.

On ski dim they have that 305 Chevy Prosport repower package they market with the powerplus trans as a way to repower old Ford boats. They mention something about a square to round adapter for the wiring harness. Sounds to simple to be true but maybe it is.

yup his name is akabulla ..it was actually fitted to an 82..but I think he used all the gauges from the boat the Ex330 came from...
He sold the boat then..Not sure if he still hangs around here though...

edit: his last visit was yesterday..so If he sees this post probably he will hace some info...

i,ve read the topic from akabulla, but there is not much info about the gauges and the wiring harness he used. I think that i can use normal analog gauges but i,m not sure.

Hi,
No Brainer to put the Excalibur in the boat. In fact it will with the right harness adapter plug right in to your current hull harness. about the only thing I can think o that might present a bit o engineering is that if the boat had a BBC that you may need to relocate your motor mount landings to accept the small block. We have done a number of re-powers in older 80's Nautiques with modern e-controlled PCM motors.
Hobby Boats can be expensive when the hobbyist is limited on their own skill and expertise.

thanks everybody for the information, It is very nice that i can use the current hull harness and gauges! The current engine is a ford 351 and not a 454.

Anybody knows where i can find a service manual for the excalibur?

Looks like ski dim has Vortec manuals, and separate MEFI manuals, as well as something they call a "Winky Blinky" for diagnosing codes. Maybe Jody, or PCM corporate could point you in the direction of an Excal specific manual:
skidim manuals

Nice looking boat! Thats an interesting motorbox cover- any idea where it came from? Ive never seen one like it.

Like Jody said, the motor mounts (SBC vs. SBF) may be a challenge... but I believe they make special mounts that allow you to put a Chevy where a Ford once was.

With a true 330hp and the lighter weight of the small block, that boat should perform nicely with that engine.

The motorbox is original for the 351. they only lift it a bit to fit the propane mixing intake.

Ahh, thats a better shot- now I see those curves in the front of the box. It still looks pretty flat on top though... strange.

Ben Their just is not an Diagnostic system cable available unless you are a certified dealer of the product that you are servicing to acquire a diagnostic system from Rinda technology's.
Excalibur motors from 2002-2005 ran MEFI-4, with the DBW in 2006 they ran MEFI-4B. 2007 to current run E-control engine management. Their really are not a whole lot of things that can go wrong on these motors that a talented tech cant figure out with a multi meter. I have gotten spoiled with the Diacom system but still keep my multi meter handy in a pinch.
I have generalized service manual for these motors that can be copied at kinkos if you want to pay for the copy and shipping.

At the moment i,m rebuilding the engine and i know that timing of the engine is cam retarded and can't be adjusted as usual. A diagnostic system would be very helpful to adjust this.

Do you have one on hand already, or are you buying new?

What are you going to use the boat for?

I will use it for wakeboarding mostly, but i don,t want to ballast it continuously. I have some props but not for the 1.23 transmission.

The 330 might have good top end, but it doesn't pull out of the hole like a GT40.

That is a true statement, but the 1.23 trans should still give the powertrain an advantage over the original Ford with the 1:1.

I would beg, borrow or steal a prop to avoid buying one before running the boat. Trying to prop an unknown powertrain/hull combination correctly right out of the box will be tough, especially when you throw in the ballast. My guess is that a 422 or similar (12.5x15.5) would be a good starting point, if you had a choice- but anything in the 13x15 or 13x16 range would work for starters.
