Author Topic:   which propeller to use on 225 Optimax

I have a 210 Outrage with a 225 Optimax, fitted with a high five 21``Quicksilver prop, doing 52knts. Whaler dealer tells me this is not the right prop, but engine does 5900rpm. They advice me a 3 blade for more speed and reverse power when needed.
Who has experiance on a better prop for this combination?

Thanks and best regards,

Holland, Europe

Hello Jorgen,

I can't help with a specific recommendation based on experience but I have the service manual for the 225 Optimax. In it is a Propeller information chart with recommendations of various propellers for different boat lengths/weight combinations.

You might want to ask your dealer for a copy or I can send you the info based on the weight of you boat, if you are interested.

One of the props for a 21' boat w/ Gross boat weight of 2900-3500 lbs is a Hi-five 13.25" dia x 21" pitch. Based on wide open throttle of 5000-5750 rpm speed 52-61 mph.

Thanks fwiw,

I think I have this prop on there right now but in 14 inch 21 pitch,doing 52 mls at 5900rpm. I can´t check because it is in winterstorage. I was told that a fiveblade has not enough opening in between the blades for speed.

What do you think?

I've not seen a hifive on a Whaler, but a lot of the "bass boat" guys around here run them, so I would think they increase speed on some boats. There are several 250 XL Optis running them.

The high five prop is used a lot on bass boats and on outboard powered ski boats. It has a great hole shot and a lot of lift. Every Boston Whaler/Merc combo I have seen at my dealer comes with a 3 bladed Merc-Quicksilver stainless Mirage or Mirage-Plus prop. Might want to give Whaler Tech support a call and find out what pitch Mirage they originally supplied on your boat motor combination. BillS

A friend of mine has a 16 foot Wahoo with a 75 merc 2-stroke. It also has a high five SS prop. This boat litteraly flies. I don't like it because it feels like the boat is overpowered.

Propellers designed for speed generally have fewer blades, not more.

I fully agree with you but I have just got the maintenance manual of Merc right now and see no difference in the speed that they claim for 3 blade mirage or 5 blade Highfive props.

My boat feels like a Ferrari when you give just a little trottle. I know that foer Wakeboarding most use a High Five
due to the torque/acceleration that it provides at start.

I also beleve that a 3 blade should run faster,but I can not find justification for that on the table in the Merc manual for propellers. The Mirage 3 blade 14.75 - 21 pitch is in the same range of rpm and speed as my high five 13.25 - 21 pitch.

I will definitly try some during the summer and will select the best prop for my use. I will put this on the forum.

For Eric I would like to state you should make time the 9th to come boating with the Dutch Whaler group. You´ll get the details.

The prop of choice for the 210 Outrage with 225 Merc would be a Mirage Plus or Revolution 4. Medium sized vent plugs should be used. These will add a couple of MPH on top end.

The five bladed High Five prop is usually recommended for water skiing applications with the V6 gearcase. It was initially designed for the bass boat market, but has been superceded by newer props like the Tempest and Trophy for those boats.
