Take a look at which bolts are in the mounting bracket.

If the motor is all the way down and using the "Blind" holes in the motor bracket, then you will need to drill new lower holes.

Then mount the motor 2 holes up.

Can't help you with prop recommendations if you don't provide the year, make and model of the engine.

I do have a load of 22 gallons of gas
1-5 people180-900( lb )
Im looking for stock performance.

Occasional water skiing mostly cruising /fishing.

May I have one or two options to choose from.
Thanks again

If you plan to have 5 people and water ski, you should probably select a 4 blade prop for better grip.

A good all-around prop for cruising would be a BPR Viper in 17" of pitch.

The engine should be mounted so the top engine bolts are in the third hole down from the top. There will be two empty bolt holes above the bolts. The bottom bolts will be in the middle of the slots.
