<h3>Bob's Machine Shop: The Original Hydraulic Jack Plate Since 1978</h3><p>Few brands in the marine performance world can claim the kind of heritage that Bob's Machine Shop carries. <strong>Founded in 1978 and headquartered in Tampa, Florida</strong>, Bob's Machine Shop set the standard for outboard motor positioning technology, earning recognition as the originator of the hydraulic jack plate. While plenty of competitors have entered the space over the decades, Bob's Machine has remained singularly focused — jack plates are not simply one product among many, but the very core of everything they do.</p><p>That laser focus has paid off in real-world results. <a href="/7266-bobs-machine-jack-plates-200590">Bob's Machine Shop jack plates</a> are engineered to improve an outboard boat's speed, hole shot, fuel efficiency, and ability to navigate shallow water — all from one transom-mounted device. By allowing precise vertical adjustment of the outboard motor, a quality jack plate can transform a boat's performance profile across a wide range of conditions. Bob's Machine offers their jack plates in multiple series — including the Standard Series, the innovative Action Series (with its internal pump design), and the patent-pending Versa Jac — to cover everything from small kicker motors all the way up to high-horsepower performance rigs.</p><p>One of the brand's most celebrated engineering decisions is their one-piece setback design. Unlike competitors that rely on spacers to achieve the desired setback, <a href="/7266-bobs-machine-jack-plates-202150">Bob's Machine jack plates</a> are built as a single integrated unit, available in 4", 6", 8", 10", 12", and 14" setbacks. All models are constructed from aluminum and stainless steel for long-term corrosion resistance, and the brand backs their structures with a limited lifetime warranty to the original end user, along with a five-year warranty on hydraulic pump motors.</p><p>Beyond jack plates, Bob's Machine Shop addresses the full picture of outboard motor control. Their <a href="/7266-bobs-machine-trim-and-tilt-units-201108">trim and tilt units</a> bring hydraulic convenience to smaller outboard owners who don't have factory tilt and trim — a practical upgrade that improves handling, reduces ramp hassle, and lets skippers dial in their running angle on the fly. The brand also produces the innovative Tilt &amp; Jac combo unit, a patented design that functions simultaneously as both a tilt-and-trim system and a jack plate from a single hydraulic pump.</p><p>Rounding out the lineup, Bob's Machine Shop produces <a href="/7266-bobs-machine-license-plate-mounting-hardware-17201">mounting hardware</a> and a wide array of marine accessories — from rigging components and electronics to trailer accessories and lower unit performance parts. Everything the brand builds reflects a commitment to American craftsmanship: <strong>all products are made in the USA</strong>, a point of pride that runs deep in the company's culture.</p><p>Whether you're a weekend angler looking to gain a few inches of motor height for shallow-water access, or a tournament fisherman chasing every tenth of a second off the line, Bob's Machine Shop has a solution designed and proven on the water.</p>

Product Details

The Bob's Machine Shop 120-150000 is a larger solenoid retro-fit kit with wiring harness, designed to upgrade existing Bob's Machine Shop hydraulic jack plate pumps to the newer, more dependable solenoid style. This kit is an ideal solution for boaters looking to improve the reliability of their jack plate's hydraulic system and eliminate common solenoid failure issues.

The upgraded solenoids featured in this kit are more robust than the original Mercruiser-style solenoids and incorporate a self-cleaning wiper mechanism that clears carbon scoring from the contact surface after each use. This design prevents the frustrating "clicking" sound caused by carbon build-up blocking a solid electrical connection — a known weak point of the older-style solenoids.

Key Features:

  • Upgrades existing Bob's Machine Shop jack plate pump to larger, more reliable solenoids
  • Self-cleaning wiper contact prevents carbon build-up and connection failures
  • Eliminates solenoid "clicking" associated with worn Mercruiser-style solenoids
  • Includes complete wiring harness for straightforward installation
  • More robust construction for long-term marine durability
  • Direct retro-fit replacement — no modification required for compatible pumps

This retro-fit kit is manufactured by Bob's Machine Shop, an American company that has been a leader in hydraulic jack plate design and innovation since 1978. Restore full jack plate performance and reliability with a genuine Bob's Machine Shop upgrade kit.

It was easy to order and it came in a short time as per ground.
