I'm not sure why this shows only in the 1990 thread. The boat is a 1986! I was the original owner and had to sell it due to injury retirement and divorce in the same month. The buyer has apparently since sold it. Can anyone help me find her again?

RE: Duals with a Ram

The 454 500HP+ models could have but my understanding was only two were ever built and sold in a boat.

I realize it has been a very long time since the question was asked but, I can tell you anything you care to know about them.
Pantera Custom had nothing to do with other builders but were tied into Panther Marine. If you find one with a another type of jet it was a swap by the owner. They ONLY came with Panthers.
The boats were originally Built and Sold in Burbank Ca in the early 80's then the company moved to Newbury Park. They closed all operations in 1991.
The only made two styles the 18' Bubble Desk (This one) and a 20 something daycruiser. I have only even seen one but we used to park next to each other at Havasu all the time.
The Big Block in the 18 was an option and required the upgraded jet. A 350 was standard. The day Cruiser only came in 454.
They had 3 454 options from 380 HP I think to 500.

Mine was a 1986 18' Bubble deck 454, 450 HP out of the factory. I redid the motor and punched it up to 950HP but that also required a jet upgrade to prevent cavitation. The Cav plate is under the jet and adjustable but not controllable unless changed but by 89 a jetovator option was available and could be retrofit

The thing could eat rocks as stainless impellers were stock, ALWAYS. The ceramic water seal in the jet was the weak point but I always had a few spares and it's an easy fix.
Good boats, fast and good on gas even with a monster motor. The 454 off the showroom could do 60mph. If upgraded out of control the right way like I did, 100mph with 4 on-board was easy.
