Ouch! A 21" pitch 5 blade runs upwards of $800 here locally. I tried looking online and these things must be rare! I'd even settle for a 4 blade and those aren't easy to find. I can get one locally for about $400 for a standard black or aluminum one. A simple 3 blade is easy to find and runs around $130 (give or take). This is quite an art to figure out the best compromise. When using my existing prop (stainless steel Rapture 14.25x23RH) I can hit a little over 50 at about 4800 RPM. I don't like to get the engine that high but I know (from reading about props) that should be the peak speed...provided I'm trimming right. I don't mind sacrificing speed. If my boat went ~40-45MPH I'd be plenty happy since I'm not out there to race. I'd much prefer a better shot onto plane.

I have one of these 4 blade variable pitch props they compromise a bit of top speed but accelerate quicker and give you a faster cruising speed

Also allows you to vary the pitch so you can do different things top speed, towing etc

I have a 08 1800SR3 with a Vensura 14x19 four blade prop. Comes up on plane way quicker than stock, way less bow rise. However with 5 people in the boat, 3 across the back and none in front it does not like it. Extremely long time to plane if you accelerate gradually. If you back off and punch it it comes up on plane OK. I am going to have to take a look at the swim platform drag mentioned.

since the swim step is mentioned...I know that filling it in with foam and then glassing the bottom of it in..smoothing it out and shaping it to be fairly flat would help alot....so..that's something to think about also...but in all honesty...I think that you are waaaaaay over propped...

Hello all,

I've just joined - specifically to find out why my 2006 1800 SR takes forever to plane, and what prop I should get. It didn't take long to find this thread...and problem. I am a brand new boater this year and have just learned that props make a difference in top end and in hole shots. I am reaching 50 mph top end but I take forever to plane out. I've read the posts and still am curious about what prop - pitch, blades, etc. I want to get out of the hole and plane quick, as I will be pulling my kids on tubes, etc. I am not worried about losing top end speed. Anyone care to offer prop choices? I'd like to stay with aluminum as I boat in inland lakes with many shallow areas and shallow channels connecting the lakes. :?:

Thanks,
Glenn

The best place to star is the Mercury Prop selector web site. You will need engine, drive ratio and size information. Your drive ratio is stamped on the side of the stern drive. I use a 17p Enertia stainless prop on my 2006 2000SR3 with a 5L V8 and a 1.47:1 ratio.

I have a 2007 1800 SR3 with much same set up ... except I have the 4.3L carb engine ... which theory says should be worse than yours.

First off I don't think swim platform will make much difference.

However I have made some small but significant changes and the boat is great - and handles like a different hull.

The standard prop is useless ... and I don't know why Maxum fit it.
Fit a Stainless Steel High 5 21" pitch .... that will give loads of low down grunt, and still allows 50mph.

Secondly I have SMART TABS fitted .... much better than fixed tabs (not sure what you have)


We ski, mono-ski, wakeboard, kneeboard & tube behind this with no problems.

Same here -2004 Maxum 1800 SR3 with 190hp carb. I fitted a s/s Hi-5 prop when I got it whic helped with low down grunt to get my unfit overweight lump of lubber out the hole better than the standard prop but the whole boat changed beyond recognition last month when I fitted a pair of Nauticus SX smart tabs - best money I have ever spent on the boat and for little more cost than a tank of fuel ! Got my 210lbs up on my mono for the first time in two years ! They really are a no brainer - fit them before you try anything else. Really makes it plane at a lower speed too which is perfect for my 8yr old on the kneeboard.
