Well I finally decided to move up to newer technology and made a deal for a Suzuki DF-70 for my 1983 Montauk. Motor is used and has been dealer serviced and checked. The deal comes with the motor, Binnacle mount with cables, 17 pitch prop, wiring harness with tachometer, the key switch, steering drag link and mounting bolts. It also comes with a short warranty from the seller as the factory warranty is expired.
In this I am mounting this myself which I have full equipment and more than enough mechanical experience to do a proper installation. The question I have is what am I missing that I will need to install and start this motor properly. I have not mounted a motor before so this will be an adventure. I want to make the best use of my time and get everything ahead done so i can maximize my warranty period.
My current set-up is a 1984 Evinrude 75 hp 2 cycle.

Last year I replaced all the fuel system all the way through to the motor so I will have to drain and flush that system to get rid of the old 2 stroke fuel.

I see a lot of people have put on 10 micron water absorbing filters instead of the standard screw on fuel filter which I currently have. Is this something I should change? I am inclined to change it.

I have the issue with the mounting of the motor in that my old motor was mounted in the lower blind holes. The Suzuki seems to be mounted from everything from Jack plates to directly on the transom everywhere from flush to what ever 3 holes up really means. I do not want to set the motor back and use a jack plate and I am inclined to mount this motor 2" up from the bottom of the boat to the cavitation plate. Will I need to plug the blind holes? I am guessing that I will not ever need to have to mount the motor lower than 1" above the bottom of the boat and I can pick a set of holes to make it all work. Is this a good plan or am I way off base? Is 5200 good sealer to seal the mounting bolts?

My battery is in the console but currently does not have a battery disconnect I am told that these motors the Emm draws power when not in use and the system should have a disconnect if stored more than a month. My boat sits a lot any suggestions there?

I am guessing that my old battery has to go it is at least 4 years old from Wal-Mart and is not very big. I am worried about power consumptions of these newer motors. Any suggestions?

I have no owners manual or service manual so I will have to find those EBay draws a blank.

My to get list at this time, manuals, Oil 5 quarts and Filter. I assume the motor will be shipped to me dry. Water absorbing filter, 5200 sealer, Fuel Line fitting to the motor.
Are there any other filters in the system I may need? I am inclined to get a water pump kit for back-up while I am ordering stuff. Any suggestions would be helpful.
For viewers reading this same questions from another site sorry for the duplicate posting.

Thank You,
