Sierra International 68357P Outboard Pressure Review

Just right to check the water pressure of my 90 hp Yamaha. Very accurate and easy to read. I removed the regular bulb and replaced it with a bright red 194 LED bulb. I've replaced all my Gagues bulbs with a red LED, red doesn't affect your night vision and looks nice too. Water pressure is the heartbeat of your engine.

If you are new to doing things with your outboard yourself, you can have your professional install it. 2: I thought they might include several different sized tees for different sized hoses. I ended up having to go to an auto parts store to buy vacuum hose fittings. 3: The hose provided is long…
