choosing the right spare prop for my Crestliner 1760 3-blade vs 4-blade

[wakeandchase]

I have a 2018 Crestliner 1760 with a 100 HP Mercury 4-stroke and console steering. It came with a 4-blade Spitfire prop as a spare, but I'm thinking about switching to a 3-blade aluminum prop. I mostly fish for bass, not trolling. What pros and cons should I consider,also, any advice on the right size?

Switching to a 3-blade aluminum prop usually gives better top speed and smoother ride but might lose a bit on acceleration

look, before you switch, you should know the difference between aluminum and stainless steel.
The Spitfire is a stainless steel prop that is way more durable and efficient. A 3 blade aluminum prop will be much cheaper, but it's more prone to dings and dents from rocks and sand.
If you're running in shallow bass waters, you might be replacing it more often.
If you can, go for a 3 blade stainless steel prop to maximise durability and speed.
