MasterCraft introduced this hull in total in 1987 as the fourth generation tournament boat. In 1987 MasterCraft added a new deck and distinctive “jet-fighter” like windshield to the hull. The new deck for this hull was flat (no hood scope) for the first time. With these changes in place, this hull did not change again until 1991.
The 1987-1990 MasterCraft ProStar 190 was about 19’ long, 80” wide, weighted about 2,200 lbs (the same length, two inches narrower and the same weight as the third generation hull).
These boats appear to have been powered by 351 cubic inch 240 hp V8 engines coupled with a 1:1 transmission (paired with a 3-blade 13 x 13 prop) as standard equipment. The 1.5:1 “PowerSlot” transmission was offered as an option. A number of engine options were also offered – 350 cubic inch (260 hp), or 454 cubic inch (390 hp/425 hp).
From 1987 to 1990 the ProStar all hulls had the closed slot or “dish” (concave divit in the hull by the prop) regardless of which transmission it had – 1:1 transmission or 1.5:1 PowerSlot transmission.
In 1987 the exterior graphics on these hulls included a colour accent strip (which included both a thin band of colour slightly above the rub rail and a thick band of colour below the rub rail that swept down toward the water line near the transom). The MasterCraft side hull decal
now had a horizontal slash through it and these boats also now carried a “ProStar 190” decal and symbol on the side hull near the transom – typically both in white), and a white “MasterCraft Competition Ski Boat” transom decal (now in a more modern Hemihead426 style font). Note the star inside the “C” of MasterCraft also disappeared from both the side hull decal and the transom decal but he word “Boat” remained singular on the transom decal.
In 1988 standard equipment included dual tournament speedometers, convex mirror, five-piece windshield
(with no centre mullion), battery, horn, automatic bilge pump, fire extinguisher, muffler system, E-Z change oil kit, fuel tank, triple fins, ski tow bar, inland lighting, blower, adjustable driver’s seat, colour coordinated carpet, centre drain, lift rings, coaming pads, drink holders, padded motor box, transom ski tow eye, side ski lockers, VDO gauges, audio oil and temperature warning, safety engine stop switch, custom rear seat, and teak swim platform.
In 1988 optional equipment included Power Slot package (see above), engine options (see above), fresh water cooling, removable brackets for teak swim platform, boat cover (colour coordinated), barefoot boom, trick release, heater, sun top, deluxe stereo package, and ‘Safe-T-Top”.
In 1989 MasterCraft introduced the WearGuard ski pylon (to reduce rope wear and make waterskiing smoother by eliminating rope ratcheting which could occur on a fixed pylon).
In 1990 a tilt steering wheel was introduced and included as standard equipment in the 1990 ProStar 190 and MasterCraft may have also introduced the first Limited Edition ProStar 190 which may have went on to become the Sammy Duvall Signature Limited Edition in 1995.
This hull was approved as a tournament tow boat by the American Water Ski Association (AWSA) from 1987 to 1990.
The 1987-1990 hull pulled:
• new World Record in Women’s Slalom and Women’s Tricks (1988)
• Women’s Jump World Record three times (1988)
• Men’s Jump World Record (1988)
According to some skiers, this hull had a “sharp” slalom wake. Although the 1987-1990 hull was also designed as a three-event hull it has a decent (but not outstanding when compared to some of the other ProStar hulls) wake for wakeboarding at lower speeds.
