TOPIC: Latest Prop Bronze 2-Blade Quicksilver

This is a Hi Performance Mercury Quicksilver prop from the early 1970's. They were meant to be a surface prop and came in even pitches of 20 to 30, in 13 or 14 inch diameter. This is a 22" pitch, 13" diameter. Took four hours to clean off the grime, sand out the factory scratches, clean up the leading edges, and polish.

If it does not work on the Glastron V-153 with 115 HP Merc, it may be too pretty to sell, and retired for display in the house.

Sweet, that came out awesome!!!!!!!!!

If it don't work for you, I'd like to try it on my 1969 Merc 1000 on my 1960 Glasspar G-3!!!

Beautiful job as always, David! Interesting blade design on that one. Prop testing with the Futura should be a blast, especially with the "new" Merc. (Spring is getting closer every day!)

Another nice find David. Did you happen to see a couple of props on ebay that are still available? The 49612A4 looked like it would be a good prop for both our boats but I thought if I bid on it then I probably would be bidding against David! Is that the same prop? The CV16 is through breakin and ready for some prop testing!

Building up a prop collection to try on Glastron V-153 next spring. Switching from a 1974 115 HP Merc to a 1988 115 HP Merc (140 HP under old rating system) and trying to find the best prop. Current speed is 53.5 MPH with 21" 2-blade bronze. Hope to gain a few MPH with newer Merc. Have 8 props to test, 2 bronze and 6 stainless steel. Props that are not fast will be sold.

Savage: looks like you have a Laser II on now - a 22" pitch? That may be better all around prop than the 2-blade bronze.

Steve: Yes, that is probably the same prop. It was on sale at the e-bay store for 50% of the former price, and I got a deal on the freight also.

Here, then, are some of the props in order: 21" 2-blade bronze, 22" Mercury Chopper, 22" Ballistic, and 22" Laser II.

SWEET!


Oh and watch your trim tab! the long ear 2 blade will hit.

That is not a Laser II. it is a Tempest 19" pitch and don't hold my rpms down. I need more pitch and something that is surface running as I have CMC trim n tilt and the motor is set up high. I have a 2-blade cupped bronze 21" pitch and a 3-blade bronze cupped, 21" Pitch also to try. This prop is listed im my Merc 1000 owners manuel but I haven't tried it yet.

Savage II, looks like my assortment of props may be the same ones you would like to try. With your jackplate, you want surface props like the Chopper, Laser II, HiPerformance 2-Blade bronze, and maybe the Ballistics. In fact, the literature on the HiPerformance 2-blade bronze says that a 15" midsection can be used instead of a 20" midsection to get the prop out of the water. My 21" 2-blade bronze is my fastest prop at 53.5 MPH at 5,500 RPM. But with your jackplate, I do not think your 3 blade or 2 blade bronze props will hold. My 2-blade bronze can break loose and the motor is only 1/2" off the transom.

I intend to raise the 1988 115 HP Merc so that the cavitation plate is about 1" to 1 - 1/2" above the bottom of the boat. At such a position, I will need a prop that holds better. Will know alot more after hours of testing next spring, and I will probably post the results here.

If the Tempest is generally a good prop, try a 21" Tempest, or a 20" or 22" Laser II.
