The price difference between a F70 and F90 is not that much. If you decide to sell the boat in the future, a F90 will be a selling point. Just consider it.
Still leaning towards the F70 but will give this more thoght. I'm a fisherman so slow trolling is important. I have stopped using a kicker motor recently. I am assuming that both engines should troll well with the slow troll feature that Yamaha has.
On a side note I have a medical procedure next week and I will be laid up awhile. This will give me a bit more time me to make this decision. Was hoping to get this done this month.
I appreciate any more input.

Hi all I just mounted a F70 on a 1980 Montauk base on reading this forum and old post of Tom Clark. It is mounted two holes up, but I ask for three dealer was skeptical. The lower bolts are threw the splash well and the motor can be raised one more hole if needed. Prop 13.25 x 14 Yamaha Performance Series. Previous engine was a 70 Tohatsu two stoke mounted all the down on the transom. Getting on plane with this setup was not good, bow up. The new set up is great slides up on plane quite and good gas milage. I have had 4 adults in the boat and runs really nice.

We'll I met with two dealers Friday. Good and bad. One is out of the running. Unfortunately they are so concerned about the China virus hard to work with.
Second dealer is my preferred choice. They understand the mounting issues with the old Whalers. They seem to have 1 hole up mounting as there method, I can battle with that point later. The bad news is there swamped and not able to get my boat into September. Way behind because of the lock down.
He mentioned something that I didn't think about. Had a customers Whaler with water damage because the lag bolts didn't get sealed properly. Something to check on my boat I guess.

In the old days, the summer is the most in-opportune time to repower. Typically an off-season/shoulder season task. Can you wait?
You can pull one bolt at a time, reseal, reinsert.
If your bottom fasteners are lags or in the blind holes you should have them filled with plugs and the lower holes re-drilled. See the mounting hole diagram in the reference section.
2 holes up at a minimum. Occasionally 3 holes depending on prop and/or motor installed.

Yes I can wait until fall to get this done. I switch to hunting so I don't need the boat.
I suppose we can take the engine off ourselves and fill the holes . I think the car engine hoist will work. But that's another small project to take on.

Engine hoist will work fine as long as it has a lifting ring. If not you may need to purchase one or improvise something with straps.
