Default 1800sr props?

So I have been trolling the web for days along with this website and was curious on any opinions of the prop Iím looking at.

To start off my boat is a Ď90 1800sr, 3.0 that will see zero skiing however fishing tubing and zipping down the river are my primary functions with 3-4 passengers.

Iím looking into a hustler 4 blade 19Ē pitch from turning point. Possibly a 17Ē for the high altitude lakes we hit. This is a new to me boat that has a 3 blade 21Ē prop currently but looks like itís been dinged more than once on all the blades so I really canít gauge what an accurate wot rpm is.

However when we had it in the water with 5 adults it took a bit to get on plane. Looking to solve that for the most part. Thanks for stopping in on this one guys! First boat for me and looking to replace the prop due to its previous hits.

Also a follow up question, What are the dang clips that go on the out drive pistons to keep it in the up position while transporting the boat?

Welcome aboard

A 21" prop on a 3.0 seems like to much IMO, what is the WOT you can achieve?

I would try Quicksilvers Prop Calculator to see what it recommends.

The drive should stay up on it's own, those devices are aftermarket and claim to reduce the load on the trim hydraulics. I would first check the trim reservoir level.

A 19P will be a good general purpose prop for you, a 17P would be best for days when you are pulling the tube. That's assuming you have the standard 1.98 ratio outdrive.
The 17P will get you on plane quickly, but you will need to watch your RPMs. There's less strain on your engine and the prop will make your boat responsive in turns.
Smart Tabs will also help get you on plane.
For your size boat, weight distribution and wind are big factors in getting on plane. Put your heavies in the bow, at least to get on plane, and start off going downwind when launching the tubers.

I wanna say with 5 adults we hit 3800 it took a good few seconds to get on plane, I know itís not a speed machine but would like to be able to hit a solid 35 with 4-5 of us. Have played around with the prop calculators and it almost always comes back 21-19. Gonna get a 19- 4 blade and take the boat out for a shake down run next week. Have yet to have the chance to take off with just two of us so it will be a great reason to crash willow beach. (And look like a clown with my trailer skills)

Going from a 3 blade 21" to a 4 blade 19" will yield little to no change. Adding a blade is additional drag and load on the engine so the reduction in pitch is counterbalanced.

Adding a blade is like adding pitch. Reducing a blade is like reducing pitch.

So would you rule out the 4 blade or just drop another pitch? Better holeshot and more responsive are the big selling points for me personally on the 4 blade.

Trust me, Iím well aware this is no speed craft. It was a very clean one owner boat with yearly maintenance records for the price I couldnít say no.
