Hi folks,
I have benefited from the many reviews of props read on this forum, so I would like to make my own contribution to the pool of knowledge.
Nothing scientific here, just my own observations of quality, performance and handling.
The Solas model 2553-141-19 prop is a stainless 4 blade, 14 1/8 X 19 pitch, with high polished finish and high rake design. It has a conventional pressed in hub and is sized to fit OMC 90 to 300 hp with the large gearcase.
My first impression was that the blades are quite thin at the leading edge, with a considerable amount of cupping on the trailing edge. It does not have vent holes for exhaust. I could hardly wait to try it out on my boat.
My rig is a 1990 Glastron 200 Futura with a 1990 Johnson GT 200 outboard. The boat is a large bowrider with room for 9 passengers. It is a fairly heavy boat and I have set it up with a manual jackplate with 6 in. of setback to help in lifting the bow.
I like to tow 2 tubes, cruise distances without wasting fuel and occasionally open her up for a blast across the water.
I have tried 4 other props from 17 to 22" in pitch with some good and some disappointing results. This one tops them all and could be a do-it-all wheel for my rig.
Before taking it out I raised the motor 1" from my previous aluminum prop setting, this new setting put the cavitation plate 1.5" above the running surface of the hull at zero trim, and proved a very good setting for this prop.
The holeshot is very good, coming on plane with little effort at most throttle settings. Not the "jump out" I get with the 17" 4 blade, but more than adequate for tubing. Handling was the best of any prop I've tried, I could not upset this prop with any reasonable maneuver, very tight turns are possible without slippage at normal trim levels and the boat seems to lift more over all. Even my wife, who was riding beside me, commented that the ride was better. When going for top speed I kept raising until full trim was reached and still no slip in straight line. I can not do that with any other prop, they will begin to slip at about 3/4 trim. When I did get slip from over trimming, like in turns or hard acceleration from low speed, it cleared itself in reasonable time and was not a problem. As you would expect, this heavy boat benefits from more trim, and this is the first prop I've tried that delivers enough bow lift to make a difference.
MPH and RPM, going by my speedo, which actually reads very close to my gps if not a bit low, I'm seeing 25 mph @3000, 30 mph @3300 and a top of 52 mph @5700, right where I want rpm to be. Now I do have other props that will push as fast, but none have all the handling qualities of the HR Titan 4. It seems that no matter what I do, this prop works.
