SeaSense INBOARD MOTOR FLUSHER

Works great

We bought a wakeboard from a guy but there was no way to get it in the water to test out the motor first. Amazon to the rescue! We bought this and were able to try out the motor in the driveway. We did read others reviews and videos about not pressing hard for suction, and allowing the motor to tighten the suction up after startup.

Used it to fire up my inboards for the first time this season. It worked 👍

Did leak but did what it was supposed to. Used it to break in new 350ci chev engine in boat. Had to leave engine running at high RPM for 30 min. Work perfectly

I bought this to flush and winterize my inboard motor and generator. It worked great for the generator, but the inboard engine’s seawater intake was too close to my bunker on the trailer, and I could not get the cup on the flush tool to cover the intake properly. Otherwise, and for the work on the generator, it worked fine. To flush with fresh water the hose connection worked great. To winterize with Marine biodegradeable anti-freeze I used a shorter hose and funnel, and climbed on the boat to run the generator while pouring the antifreeze through funnel into the short hose to the tool. Once the discharge ran pink, I shut it off. Job done. Just make sure that when you wedge the plunger in place you get a good solid and even coverage around the intake on the hull. I had to use a 2x6 and a rock to get the angle of the shaft right, but once I fiddled that into place it was fine. I cant blame the product for how the intakes sit when the boat is on my trailer - recommend you make sure you have about 4” or more all around your intake when boat is on trailer to allow room to make a good connection with the plunger cup.

Was chasing down an error code on my MasterCraft and needed to cycle a fews times (full temp, full cool) which wasn't reasonable on the lake. This let me do it in my driveway without issue. Fit snug enough to keep water flowing consistently. Idk if I would leave it unattended but I didn't feel like I needed to be holding in place either. Would work for winterizing as well with the right other equipment.

Excellent, must have item for inboard owners to winterize and work on boat out of water.

I would have given 5 stars if the rubber was larger. A larger cup would fit better on larger intakes like are on our 2021 Superair 210 making it easier to stay in place and ensure proper water flow to engine.

It does what it is supposed to and works well. I have used multiple kinds and this one works as good as other name brands. Do not hesitate here.

good

Works great ! Much better then the hook on version which was hard to get a good seal with. This one has no issues with that at all.

GOOD

Adjusts well to boat height on trailer. Does exactly what I needed it to do.
