What Comes After ?

[Sea Rider]

Scenario : A Careless Example,

This nice 2 strokes Tohatsu 18 HP was sold 10 months ago to transport boaters from a pier to their boats and viceverse, the client performing the shuttle service was strongly recommended to raise its tail after each afternoon late service, which he Olimpian Ignored. All anodes have disappered from sight, prop was spinning with resistance, seems to much salt formation between prop body and tail lower body. All water screens were nealy clogged and algae was growing all around lower tail.

If engine will continue to be used that careless way, was wondering what comes next, will lower tail eventually be eaten by the sea ? The pic speaks for itself. Careless users never learns...

BTW, Some say, Give to Caesar what is Caesar's. Jap spark plugs for Jap engines. American plugs for American engines, to each his own. Not having a NGK B7HS-10 set at hand, installed a Champion L-82C set instead, were tight gapped to 1.0 mm as they come factory gapped to just 0.8 mm, guess what, performs excatly the same as OEM ones, was astonished to hear the engine running so smooth and powerful when giving throttle. Bear in mind Champion plugs alternatives if NGK are not available.

Happy Boating

Yes, Luis, in salt, the aluminum will eventually be just oxide. That may or may not be first to finish the motor. If they treat the motor that way, imagine how poorly they service the water pump.

Paul,

After doing a 2 hour total flywheel/prop maintenence and brushing algae off from lower water intakes, the engine is peeing as a teen ager again. Tohatsu impellers are high quality, that's a real bunus. The engine has very low hours on it as the travelled distance is very short. Middle leg upwards is in impeccable state, after slight cleaning lower unit, still looks awfull. But that ain't my problem..

Another owner careless example :

This engine although has only 100 meterd worked hours has never been washed in a year use. The engine was not peeing a single drop out indicator hole. Wanted to remove LU and have a impeller look, mission impossible to revove joint pin that secures linkage. Completely solded, the only solution is to drill it.

Removed crankase from base, pan was completely salty and messy, poked all water holes as all of them were nearly obstructed. Still wanting to remove LU, was wondering if will be friendly to insert shift rod upwards given that shift rod is curvedd at upper portion and must pass through a pan grommet, must grommet be removed ? have never done this procedure before , that's why I'm asking...

Re: What Comes After ?

In our shop, we would separate the shift coupler. That may require a bit of heat and/or a fair amount of force. If you wreck the shift rod or cam rod in the process, they are easy to replace, as is the coupler.

Being the cranckase off pan will take advantage and remove LU and see what happens, if lucky shift rod should pass straight through pan rubber grommet, if not, will remove it and place it back on as soon LU has been bolted back and water grommet has made a good match with lower water tube.
