Final Review: 25HP Mercury Outboard 4-stroke EFI Motor

[@BassQuest]

Awesome. Love how excited you kid is 👍. He grabbed that net like a pro

[@retiredboxingref7620]

Your kid nailed the smallmouth with the net!!!

[@deanohit]

Great looking and sounding motor, and awesome to see your young fella so keen

[@RodneyArrow]

Hey, Buddy! I think I may have found my project boat today. Thank you for all the great ideas! You rock!

[@bassinpropaganda9210]

Get that kid his own channel he's a natural.

[@storyman34]

Great to see you out with your son. Hope to get out with my son this summer. Also, I attached a line to my trim pin, tied on and then heat shrinked to keep it in place, just in case when doing manual trim settings. Like you said, if that thing slips... into the lake it goes. (also, why am I watching boat videos in the middle of winter?)

[@mitolete6970]

Looks great Mike I did notice you had some water splashing around the motor. I had the same in my 16ft build and I had to bring up the motor vertically to the proper height and made a big difference in the performance.

[@chipsammich2078]

That boy with the net is on point.. recently my son who lives to fish has caught a devastating sickness .. Fortnite syndrome. Horrible symptoms include Won't go in sunlight Only wants to game Only watches fortnite KZbin vids. Complains anytime I ask him to do something Constantly says "I'm in the middle of a match wait a second" this goes on for hours usually.

[@ZachNMcCall]

I have the merc 4 stroke 30 on my Jon boat... I love it.

[@d.lagumbi9230]

what prop are you running?also what size jon boat

[@ZachNMcCall]

@@d.lagumbi9230 1648 Lowe Aura No middle seat just open with alum floor on ribs. I have the 4 blade spitfire merc prop... don't remember the pitch off hand. My only issue is the boat is ass heavy with the fuel tank, dual 27 series batteries and the motor. When running solo I have to trim the motor all the way down or put weight in the bow.

[@d.lagumbi9230]

Zach McCall same here. Put batteries as far forward as I could. I named my boat the basilisk. It’s the scientific name for the Jesus Christ lizard that runs on water.

I'm getting ready to buy a 2008 25 horse stroke . Do they have very many problems. It's on a 1448 jon boat . Fisher. 2008 pluse trolling motor. For. $ 3500 is it a good deal thanks

[@chrischtoph7915]

Hello, wanna buy that suzuki 20 or 25 hp for a 4,20 boat. I saw the test videos from your engines, but can you say plus/minus whats your mind and best choice to buy? I guess you lose by the 25 engine the 5 hp power more ,because the extra weight as the 20 hp... Thanks for answer. Greetings from Germany

[@chrischtoph7915]

@@TinyBoatNation thanks. The 25 hp suzuki, can you tilt the motor with no electric support or is that to heavy to do it by hands?

Hello. Good motor?

[@TinyBoatNation]

Yes, it is

[@perryjenkins2281]

Would be interesting if you would run a performance comparison of your standard 3-blade against the Mercury Spitfire 4-blade on that 25HP.

[@perryjenkins2281]

@@TinyBoatNation There are two Mercury-brand Spitfire 4-blade props that fit the Mercury 25HP EFI (2006 or newer). Both are the same diameter, but differ in pitch. The Mercury website has a helpful online calculator that will help select which is best for your boat size and weight. The two Mercury part numbers are 48-8M8026650 (9.3 x 9.5 pitch) and 48-8M8026655 (9.3 x 11 pitch). You can search for these on Amazon or check a local Mercury dealer for pricing. Mercury claim improved holeshot and holding with no loss in top speed on equivalent pitch 3-blade prop. www.mercurymarine.com/en/us/propellers/selector/#!/step-one I have a fairly heavy 16.5ft v-hull with the 25HP. My original 3-blade was 9.9x10 and struggled when boat got weighted down with just three of us and our fishing gear in the boat. The 11-pitch was wrong for me.. was too much even with just me in the boat as it slowed engine RPM a lot; but might be okay for a lighter boat. I swapped and ran the 9.5-pitch today and was very impressed how it did. Am hoping it makes a difference and when loaded with 3 guys and all our gear next week fishing.

[@johnsedler3647]

Can u please tell me what did and pitch ur using I have a flat bottom 1448 and have a 2004 Merc Bigfoot 25 tiller I tried a 10 x15 it only would go 20 mph on lake Havasu I thought a 11x 11 might b better

[@michaelbeckman1794]

I had to to change out the 1988 35hp 2 stroke mercury last year and got a used (9 hours on it) mercury 25hp elpt 4 stroke that had a 10 x 8p prop and won't get my old (1988 bass tracker, 16', guide V special) on plane, my max speed was 15 mph. I've been told to go with the 9.3 x 9.5p to solve my problems. According to all my calculations my total weight, boat, motor, batteries, etc is 1,250#. Unfortunately they don't have any "prop demo dealers" in my area. What was the diameter of your 11 pitch 4 blade that you like? Thanks and tight lines. Mike

[@varmint223]

My 16’ boat had a 12.5p 9.25 and I think a 9.9 would out run this turd I’m so not happy with this new motor

[@markcameroon6613]

lol almost knocked the kid off the boat with that hook set nice land

[@MrDavidelliottjr]

Looks like the motor was too low. The water kicking up hitting the hood. Cavitation fin should be a 1/4 inch above the bottom

[@quinthiggins5975]

Your motor may need to come a little higher . You should not see any splash coming in while your running . Cavitation plate should be even with the bottom of the boat . Shim it and you may pick up 100 or 200 rpm’s as well . Maybe 1/2’’ or more .

[@quinthiggins5975]

If it’s there then you should be about right . But it’s not worth the risk to run much higher than that. You can get a lot out of it from being in just the right spot . Have fun .

[@omieyouknowme]

My 25 yammie is 1 1/2" above bottom of Hull, I can gain another 2mph and 150rpm going up another 1/2" but I get blow out on hard turns. It's a compromise. I'd recommend a jack plate to fine tune and also get the prop further back from transom into cleaner water.

Your motor needs to be brought up, sitting to low in the water, would help a bunch

[@daniellogrono1378]

Get u a tilt and trim 700 bucks cmc dude it’s a pain to life tht motor

[@tearsofrageclan4143]

If you want more speed you need to put that motor on a jack plate. The more of the lower unit (including cavitation plate) you have in the water the slower your boat will go because of the extra drag created. Simple hydrodynamics. The water pickup needs to be just below the surface and the cavitation plate just above the surface when running at full throttle. www.boats.com/how-to/the-outboard-expert-boost-speed-with-outboard-engine-height-adjustments/

[@omieyouknowme]

Both right answers. I use a jackplate to get into really shallow waters I can still tilt motor to shallow drive with jackplate so water pickup is in the water. Will draft 3-4" with motor n shallow drive on jack plate.

[@Resistculturaldecline]

A straight ran along the bottom of the running surfaces, should extend to right at the top water intake hole, well below the cav plate. The flow of water after the trailing edge of the hull begins to rise pretty quickly. My background is decades of very fast outboard setups, and even at 100mph and the running angle of the hull, waters flow doesnt print as low on the gearcase as a straight edge would suggest.

[@aboynamedben]

take the stupid music off ur videos we wanna hear the sound of the motor and the water

[@deanfulford69]

It's slow as shit bro that's terrible

[@jshapiro34]

Faster than a paddle a vhull or John boat under 17ft doesn't really need to see more than 20mph if you can push 3 or 4 people husband wife 2 kids or 2 friends at 10 to 20 mph your beyond good.
