Most all of my out boards from late 80's up to present have an alarm test when the key is first turned. It is used to test the overheat sensor on my current motor, to let you know it is working. Usually found on motors with electric start. If you have a manual start, then it might not sound an...
Yes, running them out of water for more than a few minutes could cause overheating. Use anything that is 12v to run it down, a fan, a light, or any thing that won't overheat.
Be prepared for rotten wood under the floor, stringers, transom and floor will need replaced, as that boat is almost 55 years old. While they may look cool, those old tri-hulls were terrible for rotting under the floor.
If you plan on keeping this boat, why not do it the right way and replace all the corroded parts. Mercury has lots of good used parts floating around out there, heck, I even have a spare gimball housing in my barn for an outdrive I no longer own. Mercruiser parts are all over....
.9 mm is only .035 in sae measurement....sounds about right. .34 mm is only .013 in sae measurments...way to close. I think you have mistaken the metric and sae measurements
For long storage ( weeks) lithium batteries should not be stored full. The paperwork should spell out a desired storage voltage for long life. Also do not run them below 25% to keep a long life.
With any extra weight, it will begin to bog down and slow down your hole shot. If it were mine, I would go with the 22" and keep the rpm up near the max, so when extra weight is added you don't bog down.
Had one for years, great fun, but also had people to kayak with...they are gone now, at age 74, probably not smart going alone so I sold it a few years back.
And I was a person that used regular antifreeze and left it in the block. Gonna bet neither one if us ever had a problem ! My reason was to slow down the progression of internal rust, did it work.....?????
Got my two snow blowers ready at the season start the last two years....never used them, ended up draining out the unused fuel. Have a nice side x side with a cab and heater, lots of fun plowing snow, haven't used it in three winters !! No ice for fishing and no snow to play in these past two...
Threw in the towel today, gave up on any chance of some decent days left this season and put the boat to bed for its winter sleep. I know it is gonna be a long winter as it always is ! With the lack of snow the past few years, there has been no playing during the winter either, so gotta figure...
Unless you gave a way of hanging that weight off the stern, better use a higher weight. Remember the motor hangs over the stern, where as extra weight will be inside the stern so better add on some extra for your test. With the boat capacity shown, I rethink you will be fine, however you will...
Sounds like you have a tiller steer....so yes the weight of the motor along with the driver at the stern can make a difference. Some folks just add enough weight at the stern to simulate the extra weight of the motor and go for a test ride before making their purchase. Weight can also be moved...
Normally folks use the max capacity, less the motor weight, less equipment weight then what ever is left is for people. Motor and equipment weights are fairly constant, but people and there personal items are what varies. If you have a 300# passenger one time then a 125# passenger the next...
Pay close attention to the #2 and 3 cylinder. It has been my experience that the head gaskets blow out between those two cylinders from an overheat and a head warp. Be sure your comp gage works properly !
