While repairing my engine mount today I found the screws for the motor mount nearly siezed! My Nissan I going on 2 with only the past year in salt water. After much struggle and some grease, I was able to free them up. It looked like a corrosion issue due to the stainless screws running through an aluminum maunting bracket. I applied a liberal coating of never sieze and an will now break them free every now and then. The catch 22 for this is the fact that I check the screws for tightness all the time. They were tighter than I ever make them when they were loose. Just something to check. I never had this with my old cranky sailmaster.

Thanks for the tip. I've never given a thought to lubing the bolt threads! Our Nissan rests the winter in a forgotten corner of our basement. But it checked out okay when my son helped me mount it on Friday.

Do you have any tips on checking the level of the lower gear oil when the motor is mounted?

Do you really mean "... mounted and with the boat in the water" ? Checking with the boat out of the water and the engine mounted just requires getting the engine reasonably square to the ground.

If the boat in the water, I've heard of people doing checking and changing lower unit oil by suspending an appropriately sized plastic bucket under the gearcase. I've ever tried it that way, but imagine it can be successful if some care is exercised.

Beware of the natural attraction between water and screws, nuts, bolts and tools. Note that the attraction is proportional to the importance of the item being handled multiplied by the difficulty of finding a replacement.

Are you familiar with the check/drain/refill process? Lots of outboards have been ruined by doing it improperly.

While we are talking outboards... be sure to remove your propeller and re-grease the propshaft/thrust washers (as appropriate) every year or two.

All great advice.

I wonder how much longjevity was lost by making the new "wonder" outboards lighter. I will complete service this winter as mine will be 2 years and I will be at about 150 hours. So far, I have checked the valves and done a few oil changes. Motor has worked perfectly.
