First Impressions of Sierra International 186790 Tilt Motor
The Sierra International 186790 Tilt Motor arrived, promising a solution to a frustrating problem plaguing countless Volvo stern drive owners: unreliable tilt mechanisms. Sierra International has a reputation for producing aftermarket parts that either meet or exceed OEM specifications, so I approached this with cautious optimism. This tilt motor is specifically designed as a replacement for older Volvo Penta units, a market often overlooked in favor of newer models.
My own experience with a vintage boat restoration project drove me to search for a dependable replacement. The original tilt motor on my 1980s Volvo Penta AQ260A had given up the ghost, leaving me with a non-functional power trim system. This meant manually wrestling the outdrive, a task nobody enjoys, especially after a long day on the water.
Unboxing the Sierra International 186790 Tilt Motor, my initial impression was positive. The motor felt robust and well-constructed. Its weight suggested a solid build, and the finish appeared durable, hinting at resistance to the harsh marine environment.
I considered other options, primarily a rebuilt OEM Volvo Penta motor and a generic “universal” tilt motor. The rebuilt OEM unit was significantly more expensive, while the generic motor lacked the specific compatibility assurance of the Sierra International model. Ultimately, the Sierra International 186790 Tilt Motor seemed to strike the best balance of price, performance promises, and compatibility with my older Volvo stern drive.
My first impression leaned towards excitement, tempered by the understanding that the true test would come during installation and operation. I hoped this Sierra International motor would deliver on its promise and breathe new life into my classic boat.
Real-World Testing: Putting Sierra International 186790 Tilt Motor to the Test
First Use Experience
The initial testing ground for the Sierra International 186790 Tilt Motor was my own boat, docked in the brackish waters of the Chesapeake Bay. Installation proved straightforward, mirroring the process for the original Volvo unit. I followed the provided instructions, and within a couple of hours, the new tilt motor was wired and ready for its first workout.
The difference was immediately noticeable. The motor engaged with a smooth, powerful whir, lifting and lowering the outdrive with ease. Previously, the original motor struggled even under ideal conditions. I tested the motor repeatedly, cycling the outdrive through its full range of motion, and the Sierra International unit performed flawlessly each time.
There were no immediate surprises, which in this case was a good thing. The motor felt strong and responsive, restoring the convenience of power trim to my aging boat.
Extended Use & Reliability
Several weeks of regular use have passed since the initial installation, and the Sierra International 186790 Tilt Motor continues to perform admirably. I’ve used the boat in varying conditions, from calm, sunny days to choppy waters with moderate wind. The tilt motor has handled it all without a hiccup.
So far, there are no signs of wear or tear. I religiously inspect all components of my boat, and the motor housing shows no evidence of corrosion or damage. Basic maintenance involves periodically checking the wiring connections and applying a corrosion inhibitor to exposed terminals.
Compared to my previous experience with the failing original motor, the Sierra International 186790 Tilt Motor is a revelation. It provides consistent, reliable performance, making boating far more enjoyable and manageable. It certainly outperforms my expectations, especially considering the significantly lower price point compared to a rebuilt OEM unit.
