Their rep is a pleasure to deal with: Michael 804-436-0150 www.varipropusa.com
I found out about Variprop from a study that compared drag etc. of all the major brands and did some other comparisons.
Some of the advantages:
- You can set separate forward and reverse pitches (I use slightly less pitch in reverse to reduce prop walk)
- You don’t have to dissassemble to adjust pitch (take out a set screw and turn another screw)
- Very short hub
- Some others I forget
They can even make a 4 blade so you can get adequate blade area in a small aperture.
You give them your engine and transmission info and their german engineers recommend a configuration and initial pitch settings.
I got a 15.5" 3 bladed. The original fixed prop was 16 and was very close to the top of the aperture. They’re standard sizes are in inch increments but they customized reducing the 16 to 15.5 at no additional charge.
I’ve been extremely happy with it.
Alan

What size did you get? Did you get from Variprop? How are they to deal with?

I have a 33 and put a Varifold 3 bladed feathering prop and am extremely happy with it.

Prop - my preference would be the three blade. They will typically drive the boat better into a chop.
Blistering - TPI went to vinylester resins in '85 (I bought the first Mull 36 delivered to a customer in ‘85). Your 86’ 30 should be fine.
Waterline - I now own a '87 F30 and had to raise the waterline to carry the loads for longer cruising. Evenly balanced, I think I brought it up about 2.5 inches. I doubt is this is unusual.
Good cruising!

Hi to all Freedom owners, most especially F30 owners.We are the new and very proud owners of F30 #12, NARISA,ex SPIRIT, owned for 18 years by Marty Levin ofMilford, Connecticut.I have scanned and searched through all of the very usefulemail files of this Freedom Group but need some specific helpon our preparations for a trip to the Bahamas this Fall.1. PROPELLER: The current prop is a 14 x 14 fixed blade "sailingprop (on the original Yanmar 2GMF20 with 2.62:1 gearbox). I want thebest of both worlds, sailing and motoring. Currently looking at a KIWIprop from New Zealand, which is a 3 blade feather unit, and a Flex-O-Fold 2 bladed folding prop. Any suggestions from F28,30,or 36owners?2.OSMOTIC BLISTERS: To epoxy seal or not to seal, that is thequestion. When surveyed, this boat showed no sign of blisters. I haveheard that TPI moved to vinylester resin sometime in 1986. Any ideawhat boat number? We will soda blast 19 years of bottom paint tomorrowand I have a chance to seal the bottom. Any advice from owners?3. WATERLINE: Lightly loaded (no dink on davits, half water andfuel)this boat sits almost exactly on the stern waterline with bow upabout 3 inches. Is this normal trim? Thinking of raising the waterlineAND loading a bit more forward. Any advice?Any other thoughts or ideas for a detailed preparation for this tripwill be put to good use.Thank you for my daily Freedom mails.Narisa and Fargo RousseauBlue Hill, MaineChiang Rai, Thailand
