Propeller Recommendations

I love threads like this.

So I see a few things:
That strut looks nice and massive, the barrel looks plenty long enough to take a longer cutlass bearing, hoping you can get it bored for the bigger shaft? Are the bolts accessible from the inside?
The gap from the forward propeller face to the aft face of the strut barrel looks too large, normally 1 x shaft diameter (2-1/2”) is max, 1-1/4” is preferred. You can adjust the overall shaft length on the new one to take care of this issue, double check before you order.
The thin jam nut is in the wrong location, it should be first and then the large nut should follow, about 50% of the shipyards seem to get that right.
Minimum prop tip clearance range for a non-tunnel design is typically 15% - 20% of the prop diameter. So for a 28” prop, that is 4.2” to 5.6”.
Make sure your new prop is setup for a Propsmith puller tool.

You shouldn't need to change diameter if the boat has no issues getting out of the hole or staying on plane with what you've got. I've run both Veems as well as michigans,, federals, etc. Veems would be my instant first choice. I've run both the normal and the interceptors. In your situation the Interceptors might be a good choice as you can easily change cup. While you're at it, I'd soda blast the bottom to gelcoat and put new barrier coat and bottom paint. It looks like you have a lot of layers of paint. I did it on a 26 knot cruise on a 2007 62' that had a lot of layers and the boat picked up 2 knots and cruised at 28 knots back in 2014.

It's the " while you're at its " & the " might as wells " that sneak up and cost you too.

I think Viking is predominantly Veem Interceptors, they have a great following for SF over 30 knots.
The advantage is that you can account for increasing or decreasing load by exchanging the Interceptor inserts: https://veempropellers.com/interceptor-technology/
It has been around long enough that I would consider it a proven product.
A good prop shop should be able to spec a prop that is very close to your needs. They should be able to specify the pitch within 1", if they miss it you should have an agreement ahead of time. You don't want to be on the ticket for a new prop and then have to take out more than an 1" of pitch IMO.
Another thing to keep in mind - you want to avoid at all costs the Propeller Hub diameter being larger than the Strut Barrel diameter. This is a significant contributor to Propeller Blade Root Burn at the hub and is easy to overlook.
I would also consider the Federal line from MW: https://www.miwheel.com/propellers/brands/federal-propellers/ To see what fits in your budget and delivery times.
A 31 -32 knot WOT sportfisher is not quite as challenging to prop as the 40 Vikings/Hatteras or 45 knot custom Sf like Spencer, so you have some leeway in your selection. Would pass on other brands for this application.

Adam, FYI we are spinning 33's so you shouldn't have any problems with fit. But it did take multiple try's with props to get it right. Started with Michigan wheels then ended up with Ellis props (no longer in production). Would be nice to try out Veem someday.

Great information.

Keep in mind that Donzi 54 mentioned he replaced his struts during his repower (I recall), so you may not have the same amount of drop to clear a 33" Diameter Prop plus a minimum 15% (4.95") Propeller tip clearance > total drop from shaft centerline is 33"/2 + 4.95 = 21.45". Maybe Donzi 54 can shed some light on what strut he used?

Curious to see what the other prop guys recommend, a quick calc on my part is showing 33" x 40" but 5-Blade, but this will depend on each manufacturer Blade Area Ratio. My calc only has a BAR of o,85, kind of on the light side.

Something you should look out for. Check your rudders closely, where the rudder shaft goes into the rudder blade. If you have the same stainless rudders that I originally had, they had started flexing and developed stress cracks. They were made of thin stainless plates. I change mine out to a set of much stronger Western Branch rudders.

I recently started looking though my rather large file of invoices. That was one item that only specified the cost of the struts. I will recheck if there is other info on strut manufacturer. My guess is they used the same strut that Roscioli was using at that time on the 58 footer being that the 12v2000 was what they where installing

I can get your that info. They where replaced well after the engine replacement. They were a simple swap. W/B website has all the info on how to size.

I would go with Veems for the props. A lot of different new boats I've been running spec out Veems……..the veems run very smooth throughout the range and perform very well and have great metallurgy. The michigans/Federals seem to bend blades if you touch anything with them (2x4" size log, etc.)

Those are nice rudders, quite an improvement of flat plate designed rudders.

Looks like a great choice to me
