Yamaha Oil Points-- 100-Hour Service
Paying mercury outboard motor propeller to Yamaha oil points is the last 100-hour service action. It is suggested to grease your engines' oil fittings much more regularly than your 100-hour or yearly service, yet if you haven't, currently is absolutely the moment.


See to it you have lots of Yamalube marine oil loaded in your oil gun and also start hitting those Zerk fittings. Note that installations can be infected by salt-- especially the ones near the steering tube-- so replace them if they are too worn away to accept grease. View as you pump fresh oil into the fitting and see if old, dirty oil or water or both push out from the corresponding space. Preferably, these tooth cavities are full of tidy grease all the time. A light coating of oil on the pointer of the trim rams will reduce friction there as well.

Next, remove the cotter pin from the propeller and loosen the prop nut. Exercise severe care as the prop blades can be very sharp. With the nut loosened up, get rid of the prop and linked prop hardware to inspect the prop shaft. Try to find fishing line that may be behind the prop and near the prop shaft oil seals. Get rid of any kind of that is spotted and if the seals are undamaged, use a fresh covering of oil to the prop shaft prior to reinstalling the prop. Tighten up as well as make use of a new cotter pin to complete the installment. This is additionally a good time to evaluate your exterior engine anodes. If prop for 40 hp mercury outboard are put on past 50%, they are spent and should be changed.

On the powerhead itself, Yamashield Corrosion & Rust Protectant can be freely related to the metal surface areas-- taking some like avoid the air intake itself. If any kind of salt residue exists in the engine frying pan, wash with a light stream of freshwater before using Yamashield. This item additionally functions well on battery links, fuel/water separator bases, as well as trailer parts.
