1988 Outrage 22 Whaler Drive E-TEC 200 H.O.
Posted: Wed Aug 28, 2019 12:05 am
I have an [1988--please use four digits for years] Outrage 22 Whaler Drive with an [2006 E-TEC 200 H.0. engine with] 25-inch shaft. I need advice on propeller selection.
The engine mounting height is good.
The current propeller is a REBEL Rebel 15-1/2 x 17. The engine can only accelerate 4,900-RPM or maybe to 5,000-RPM down sea and down wind. Engine speed data is via a Lowrence HDS Gen3 via NMEA 2000 and is confirmed on my RPM gauge.
I know my target engine speed for this motor is 5,500 to 5,600-RPM at full throttle.
My hope is improved fuel economy fishing offshore. Currently getting 1.6-MPG, which based on my reading, is abnormally and excessively low. But I have lots of (expensive) data points confirming this.
Based on research estimates of engine RPM changes due to pitch, diameter, number of blades, I used 200-RPM change for each inch of pitch or diameter or number of blade changes. The change in RPM I want to make is +700-RPM.
I'm looking at the Viper 15 x 14, three-blade. I would like to try the four-blade Cyclone 14-1/2 x 15 (but I think it would leave me shy about 200 to 300-RPM. Of course these are based on my approximations for effects.
Is there any real world data on effects with a similar combo out there?
Some additional info about my boat that I think factors in:
I've read a lot and everyone seems to run or suggest a 17-pitch propeller, but that's obviously not working for my boat. My guess is that the foam on this 1988 OUTRAGE 22 Whaler Drive boat is totally waterlogged.
In its past life, the previous owner had the OURAGE 22 Whaler Drive boat moored in Newport Beach and a large knot head sea lion lived on it. A big one, like 700-lbs. A lot of the back of the boat would be under water and it was there for years--or so I've heard.
A few years ago I replaced the fuel tank and had to cut a couple holes from the fuel tank well to stern floor compartment, and another hole from that compartment to the rigging tunnel section on the starboard side. During that process, I confirmed the foam is wet. Bummer, but it is what it is. Someday I'll go weigh the boat somehow.
The boat has T-top, 77-gallon fuel tank, 45-gallon bait tank mounted just behind and partially under a leaning post, terrible bottom paint chipping all over the place but stored on a trailer. I usually run with two other guys but hardly makes a difference with fuel economy. I actually have no complaints about power, getting on plane, or top speed. I never run at full speed 40-MPH.
Since the last time I was on here, I've replaced the fuel tank, re-wired the boat, power coated T-top and leaning post, installed new under deck plumbing bait tank, overhauled the teak gunwales and rear hatches with varnish, new electronics, and other minor improvements.
Any advice on a prop would be much appreciated.
I'm also looking for a place that will let me try different props until I'm properly fitted.
I'm in Orange County, California
