Greetings
Im wondering if mercury sells a "kit" that would make my 150 mag efi mariner 1998 model year engine a 25" instead of a 20" transom setup?
Reason being is that when at dock, theres only roughly 4-5 inches of clearence between the water and the top of the transom where the motor mounts. The transom then raises up even higher the rest of the way to the side of the boat on both sides, but in decent waves, 1 - 2 footers water will occasionally come over the transom into the splash well..literally come over, not just "splash". While i understand it would take some decent waves / water to sink my boat, it still isn't comforting to see this happening. The boat is a 1800 sylvan elimantor...very deep boat, but they elected to use a 20" transom which STINKS. a 25" would of been perfect). The boat is rated to a 150 which is what i have. Of course when i bought the boat i never thought about the transom height, but lesson learned.
What im thinking of doing, if such a kit exists to make my engine a 25" shaft, is to install a jack plate using the holes existing in the transom, then mount the motor on that with a 25" shaft, then using the jack plate raise the engine ~5" so the drive is properly positioned again. Once this is complete i could then weld in some aluminum sheeting to cover the drop in the transom where the motor use to mount, which in turn raises my transom another 5" giving me near a foot total from water to top of newly raised transom. Since the transom was designed to be 20". the additional 5" i would fabricate wouldn't need to be load bearing since it's just acting as a splash guard essentially...
Thoughts? I will attach pix later tonight if that helps. All this rides on whether or not they make a kit...which i kinda doubt...
