Rinsing engines

[dan_hoog]

I had my engine / mechanical stuff treated with t-9 a couple times since purchase. I've heard several people suggest rinsing the engine area.

What is the process I should use? Would it just be low pressure flow right over the engine? I'm just not sure where to run water or what to avoid, so I've left it alone. Everything looks fine, but I suspect it needs it by now. I boat in salt water and store on a lift. It seems I should rinse and reapply either t-9 or crc heavy duty corrosion protection.

Any advice or comments would be appreciated.

Best,
Dan

I always rinsed my engines a few times a year. Along with coating them with T9 a couple times a year. As long as you spray a cold engine and don't hit anything with high pressure, I don't think anything under there can get hurt. Probably don't need to hit the electronics on the back wall though.

I regularly boat in salt water, when I do, I flush both engines, fog them just tad, rinse them down and put the boat away with the hatch up, so everything can dry. After a few days, I come back and coat everything with T-9 including the wires, manifolds, tubes, etc.. Then, I'll coat the jet drives. Takes me an extra few minutes, but it's worth it when dealing with salt water. If I were boating in fresh water, I wouldn't rinse the engines down nearly as much.. Still make sure they're coated with T-9.

Here's the way I look at it, these engines are from Waverunners, designed to get WET! All the electronics are sealed. As long as you're not pumping water in the intake, oil fill or pressure washing your electrical circuits, you'll be fine.

@dan_hoog -
I only boat in salt/brackish water. I rinse my engines through the ports every time and have only "rinsed the engines" once. I do have them protected with the Yamaha spray and wipe them down, but they never get wet externally so maybe a wipe down here and there but for the most part I wouldn't excessively worry about it. About every 3-5 runs I do detail my boat and that's when I wipe down everything. Engines included.
