NEW Motor by JP MARINE...Pics inside New
« on: May 04, 2010, 05:49:27 PM »
I am on these boards all the time but never post.  I though this would be a good time to post.  I have owned my 79 Hondo for over 7 years now.  I purchased this boat from JP Marine, when he had just completed the resto on it.  The original motor was a mild BBC 468 (stock intenals) with a holley 600 CFM double pumper with about 380HP.  What a great motor never gave me any problems for 7 years and I drove it hard.  Unitll last OCT when I went out for one last time and it blew...and I mean blew.  I ended up breaking an exhaust valve and sucking it in to the block.....which lead to all kinds of damage.  SOOOO.......What a great time to build a new motor.  I went back to Joe at JP Marine because I trust him and I believe he is one of the best jet boat builders out there.  

NEW MOTOR.....whoohooo!!! ;D

496 Stroker at about 600HP  I changed to a chrome 850 Holley and upgraded to all forged internal and rollers.  New pipes to becasue the old one were shot and I had to have shinny new pipes for the new motor.  I spared no expense on this motor and it was worth every penny!!  Took it out to EL Cap and only opened her up about 1/2 way and WOW the difference was awsome.  Gonna give her a little more time to break in before I really push it.

I saw this boat last week at JP's and the pic's do not do it justice! That is a really nice clean looking boat! I had just commented to Joe about how much a new set of headers really set off a good looking boat.

No, thank you for the concern.  The thought of water getting into the MSD was talked about when he mounted it there but JP has never had a problem with that location.  It doesn't get that wet there.  I was going to get the "Marine" one, but DAMN its like double the cost.  I had this same unit in my car and use to power wash the engine all the time with no issues?  I was thinking about putting some type of silicone or even some vasoline around where the wires are to reple the moisture.

The Marine one is sealed to protect it from causing spark and avoiding fire/explosion and is a must with a sealed engine compartment and some say a must on all marine use, Including most Coast Guards and water craft enforcement. I spent the extra cash just for the lack of hassle reason alone.

Some might say that's not a good place cause of the heat and vibration also along with the constant temp/humidity change might/could cause condensation to form inside the box causing problems.

When I saw it I thought it looked cool and thought about the down falls of putting it there because I need to mount mine soon and was wondering myself.

Hope others chime in because I don't know if I'm right or wrong.  :)   Does look cool, Nice float, Welcome to the site..      Roy

Yeah the water level is way up.  I think its from San Vincete because they have been doing work on the DAM, and the rain to.  That RAMP is STEEP to.  I liked it when the water level was lower and they had the beach area to park near the other ramp.

Very nice!   What impeller do you run and how many RPMs will it turn with that impeller?  Thanks.  BTW.  What is your top speed?

Interested to know how the boat did with a droop.
My understanding was that those hulls dont like the thrust out that far.
Anywho...
