Outboards in Salt Water Question.....

Joe posted the following in the other thread, but I thought I would start a new thread so as to not mess up the other one.

I have a question along this line. We just ordered our new outboard yesterday from onlineoutboards, a 9.8 HP Tohatsu with electric start and the ultra long shaft. We will be in fresh water over the summer, but hope to be in Florida next fall.

The boat could be in the salt water for up to two months. Normally we pull the motor up as soon as we start sailing unless we forget to do so :cry: . We also pull it up at night. In salt water would it be better to leave it down in the water at night and also if we were just sailing a little or sailing slowly where it wasn't hurting us that much?

I wonder if there would be less deposits/corrosion inside if it just stays wet and doesn't go through a dry/wet cycle. Or does it not dry out that much in a day on the inside anyway. I haven't seen anything posted about what is best in this respects.

Thanks,

Sum and Ruth

Sum,
I'm looking at getting the same motor and was wanting to get your input on what you're getting:
1-Why the ultra-long shaft (for the ocean?) and will this affect your lake sailing?
2-Are you getting the remote controls as an option?
Thanks

I'm going to make a plate that is easy to remove on the transom that will raise the outboard about 4-5 inches and set it back 3-4 inches. That will allow it to sit higher and be easier to operate from the laz seat and will also allow it to rotate full lock to lock.

If you put a long shaft 8 or 9.8 Tohatsu/Nissan in the stock well on an S and probably a D it won't quite turn lock to lock as it hits. It still probably turns fine for tight maneuvering while docking using it in conjunction with the rudder, so it will work. Raising it will just work a little better.

Then when we go to the ocean I'll pull the plate off and put the outboard down on the transom and give up a little in the maneuverability for the added depth in the water.

Walt got a 9.8 earlier this spring and we talked about this mod then and he has done it and seems to be happy with it. I'm going to do my plate a little different so that it is easier to remove and you won't have to get into the laz to do it. I'll post pictures later on my site.

The ultra long shaft comes with a 5 pitch 4 blade prop. I also ordered a 7 pitch 4 blade prop and will try them both. I also ordered a prop kit.....

....... 10 micron filter/water separator at the same time. The shipping on them was free as I ordered them with the outboard. The filter was cheaper than the other filters I've been looking at. A while back we discussed on here where to put the filter in the line and he told me to put it between the bulb and outboard for what that is worth

I belive the long shaft comes with a 3 blade prop that probably isn't as well suited to our application.

Sum - my BF and my Nissan 4 HP get about one month per year in salt on the Cape each year - im on the original zincs and leave the motor down at all times. I dont think its a significant issue. Stray current in marinas is a much bigger issue.
