    (34)Prop(34)erly Equipped-gctid811243

    Took delivery of a new to me 2052 (1996) in mid April. Very well taken of with low hours. Just wrapped up the major PMs I wanted to perform before summer boating hits its stride, including:

    - changed engine oil and filter

    - changed plugs and plug wires

    - changed fuel filter

    - changed impeller

    - changed gear oil

    The last project was to find a prop I liked better. Although there really wasn't anything wrong with existing prop (3 blade Black Max - 14" x 19" pitch, I thought it was slow to get on plane.

    First try was with a Solas Amita 4 - 14.5" x 17" pitch. This wasn't the answer........ over reved the engine to 4,800 - 4,900 rpm and lost over 5 mph in speed.

    Next try was a sweet success! I put on a Mercury Spitfire 14" x 19" pitch. Boat nearly jumps on plane, as it takes about 3 seconds to get there. Added benefit is that actually added top end speed over the three blader with about 3-5 mph more. The only curiosity is that for the most part, she pegs out at 4,500, on a jaunt with some time at top end, she will hit 4,600 to 4,700 rpm. Although, this is the same as with the Black Max 3 blade, so maybe not a curiosity after all.

    Outside of testing and running from the rain, I don't keep it firewalled, so I was wondering if anyone thought trying out the Spitfire in 21" pitch would be remotely worth it? The boat was pretty lightly loaded with two adults, a teenager and a poodle. My thoughts are that I found the sweet spot and I'm pretty darn happy. The other reason I thought a 21" pitch would be a waste is because hole shot would likely suffer and with more passengers and gear would negate the ability to eek over 4,500 rpm. Finally, if we start pulling a tube, the 19" pitch would be just right.

    Having said all that, I'm really pleased with the Spitfire. Seems to deliver all that's promised for a performance, aluminum 4 blader. If you're looking for for a prop, you might want to consider trying one. If anyone needs a 14.5" x 17" pitch 4 blade, I know where you can get one reasonably.

    That's my story and I'm sticking to it!

      Thank you for posting........ I've read many of your posts and appreciate your knowledge and insight.

      Actually, I think I'm golden....... I thought the manual listed 4,500 rpm as max. But looking at the engine nameplate per your suggestion, it states 4,400 - 4,800.

      You gotta love it when the answer stares you straight in the face!
