Wanna SS

[WIMUSKY]

Boat: 2003 Crestliner 1650 SC Fish Hawk deep v
Motor: 2003 60hp 4 stroke Johnson
Prop: AL 14x17p(I believe it came with the motor when new. No model name)
Rated WOT rpm: 5300
Actual: 5300(maxed w/full load)
Want to accomplish: A better hole shot.

I know this is doable even tho it is a 4 stroke. I've proved it by adjusting boat setup. My main issue is weight distribution. It's tail heavy with the 4 stroke and boat design. Crestliner has since fixed the issue by relocating the tank, so I've heard. I have no weight to relocate. I don't want to use a hydro foil or tabs. I also don't want to add weight. I will lose my storage if I do. My hole shot isn't bad, therefore, I think it can be propped to accomplish my goal. If I put my daugher in the bow(all 3 of us in boat), or, just have me and her side by side it planes out good.(She's only 100# soaking wet). If all 3 of us are boating and she sits in the seat behind us in the center, I lose a decent hole shot.

Below are the OEM choices for my boat along with a description of each style, plus a layout of my boat(bottom of post. Pic is deceiving, it does have a 87" beam). I know this is info overkill, I just hope some of you knowledgable members will take the time to look it over.

Considering I'm currently at max rpm at WOT, one would think to go up in pitch, 19p. But, I don't want to make my hole shot worse. I "rarely" go WOT so if I exceed the rpms a little I can adjust at throttle.

I think the raker is out since I don't need more bow lift. I can barely trim it up as is without porpoising. Although, the bow will come out of the water more than enough as to not plow.

Right now I'm leaning towards the Viper 17P. What say you? Or, should I go to a completly different manufacturer?A huge thank you is an understatement.....

SST - Stainless Steel Props: (Stainless Steel Tough)
- View Chart -
A Stainless prop will last longer than an aluminum prop, plus offers greater performance - beneficial for avid boating and water skiing. Has a "Thru-hub" exhaust and 3-blade painted stainless steel design. A low pitch propeller that comes standard double cupped, and is also available triple cupped for pontoon applications. SST props are repairable if damaged.

The SST propeller is 5 times stronger than an ordinary aluminum prop. The blades thinner are thinner for a cleaner bite to achieve higher top end speed. The SST is a fast planing prop with thru-hub exhaust and cupped blades. More expensive than aluminum, but highly recommended for the serious boater.

SST II:SST II---Double cupped blades on the SST II propeller let the user trim out more for greater speed. The outboard can be mounted higher for peak performance with less slippage then single cupped blades. With the SST II propeller, more MPH means more MPG. Boats go farther as well as faster on each gallon of fuel. Like the SST, the SST II propeller features super thin blades for cleaner bite and extra thrust; yet they're still 5 times stronger than aluminum.

RAKER Stainless Steel Props:
- View Chart -
3-blade propeller (highly polished), thru-hub, stainless steel prop with high blade rake to increase bow lift. For bass, runabouts or high performance boats. Ideal for boat applications over 50 mph in V-4 and V-6 Evinrude and Johnson outboard engines.
Rake is the measurement of the angle of the blade's tip toward or away from the gear case.
The custom cupped high rake blades provide superior bow lift and make your bass boat or high performance runabout plane fast and run fast. Made from aircraft quality stainless steel. The outer exhaust hub has drilled holes to ventilate the three highly polished stainless steel blades for more powerful acceleration.

VIPER Polished Stainless Steel Props:
- View Chart -
3 blade performance, high lustre finish - Made for speed!
Its longer swept blades and a larger diameter give this prop a better grip on the water, faster acceleration and greater top end speed. It's fast out of the hole and delivers maximum top end speed. Excellent on any recreational boat, from runabouts and cruisers to deck boats. A good choice for Evinrude Johnson V4 and V6 outboard engines.

Re: Wanna SS

I'm bumping this up. There must be some opinions out there.......

Re: Wanna SS

I would think a 4 blade would be helpful, the ones I have tried have been great with holeshot and have helped lift the boat all around. A 15 would be great if you could rev to 5700. But if you want similar or slightly less rpm, stay with a 17. Props I have tried and like are Solas Amita 4 aluminum (bargain priced) and Solas HR Titan 4 stainless, still cheaper than oem. Certainly there are many other choices but where price is concerned, these are hard to beat. Search reviews of these and other 4 blades. The only down side may be a drop in RPM due to the drag of the extra blade, but a good design will make this up in reduced slippage.

Re: Wanna SS

I'm with Vista on this. Stay with the 17. If you go with a 4 blade you can probably get the engine up a couple of holes.

Did you see trendsetters titan review?

That is my only reservation about a 4 blade on a 4 stroke considering a 4 stroke already lacks out of the hole rpms that a 2 stroke does. My AV plate is even with the bottom of the hull. I could raise the motor as Bailey stated to help compensate for the extra blade. Are my concerns valid? Or, would a Solas HR Titan 4 eliminate that issue?

I'm assuming trendsetters review was for a 2 stroke....

Thanks for the replies.......

Re: Wanna SS

Sorry musky, only 2 stroke experience here. But I can say the 4 blades will work with a higher setting, 1 or 2 holes up for sure.

Re: Wanna SS

Thanks for the info, vista. I was hoping someone used a 4 blade on a 4 stroke OB and had an idea whether it was good, bad or otherwise. Going up a hole or 2 shouldn't be a problem I believe the AV plate is pretty much even with the bottom of the hull. I guess, at the moment, I'm still on the fence whether to go with a more aggressive 3 blade or bump up to a 4. Now I have all winter to contemplate it.

Re: Wanna SS

Hey, WI MUSKY, whats up? I'll let you in on my running experiment. My dealer hooked me up with a turning point 13.25x17 Express SS, could only get 5250 max (35mph), the bow lift is unreal (loves weight in front). My set up for years was a group 30 battery up front with a 50#mk trolling motor & a 20# "river" anchor keeping the battery company. Other than that most gear was placed as mid drift in the boat. This last season I lost the voltage regulator on the motor the 3rd day into a 14 day trip in Canada, the camp owner let me carry a group 27 battery as a back up (up front). I seen a 1/2 to 1 mph loss in speed, but the nose felt better at speed. Since coming back from that trip my prop tests have started. I contacted my dealer a couple weeks back and told of my results with the Express, now he hooked me up with a 13.25x15 Express (old style, used, $200 cheaper) Results: 35mph @5650.... for laughs I decided to remove my "whale tail"and try again... interesting.... now I can get 35mph trimmed under... without porposing!!!! But I'm still not trimmed even (as measured from the hull even with the cavitation plate)... so with some research and some hopeful insight??? I've invested in some trim tabs (navonics smart tabs), I'll bolt them up tomorrow and see what I get. Bottom line is: Factory prop... no amount of trim under made the porposing stop... added foil... it was better(not perfect). Alone I could achieve even trim on the motor... and 36mph... with 2 guys... 35mph best.... under ideal conditions. New prop...(13.25x15 Express)... more rpm (good) can trim up a little without porposing (great).. when she starts to porpose...35mph... speeds available above....yes!! If I can hold down the nose.. Ican see a minimum of 1 - 2 mph gains...maybe more. She hit 36mph and was climbing steady before I had to back off of "even trim" without the "whale tail" on the motor. I will post results probably Sunday afternoon.

Re: Wanna SS

Resurrecting my old thread since I still haven't bought an SS prop and this thread has all my boats particulars.
Here is what Iboats recommends:
http://boatpropellers.iboats.com/Jo...=2&search_blades=&search_rotation=1&x=12&y=12

Of those listed, which would you recommend to get on plane a little faster? I'm ruling out a 4 blade.

What about a venting prop? My brother has the same boat but 1 size up. He's a foot longer and a few inches wider but runs a 125 Merc(max for his hull) with a Laser II venting prop. His boat pops right up. Granted, he has at least twice the power. As far as I can tell, the Laser's smallest pitch is 19. I need a 17. Any other venting prop that would fit my specs? Looks like in a SS I need a 13 1/4x17(going by Iboats recommendation). It currently has a 14x17 AL which is perfect for rated/actual rpms.

Thanks............
