BIG Question - replace Yamaha 150 HP with Honda 225HP

Pike-Hunter · #1 03-19-2008, 01:20 PM

This is a great forum and I just signed up this morning and I am eager to learn as much as I can from the gang on this forum.

First, I have a 2004 Wellcraft V21 Steplift powered by 2003 Yamaha 150HP TXRC. Also a trolling motor Honda Four stroke 15HP for catching salmon and trout on Lake Ontario.

I was entertaining offer on trade in with Honda 225HP 4 stroke engine. This outboard has the best displacement of any given 225HP.See quote below:

New 2006 225 HP Honda - 25" - MSRP $18,389.

Discounted Sale Price $15,450.
Less 150 Yamaha - 5,800.
w\25" Shaft $9,650.* Plus Tax
Model TXRC

*Includes Installation on boat with Honda Controls & Gauge Package & 3 Blade Aluminum Prop as required - Engine qualifies for Extended Warranty to 5 Years at N/C (Value $2,300). Must be registered by 3-31-08 to qualify. Also $500 rebate offer on this one.

My biggest questions:
gas savings?
performance wise?

Am I better off to leave this outboard the way it is?

Thefermantor stated I was not wise to do this. Hence, this is why I am posting a new thread. Am I fool?

Thank you for your anticipated feedback.

I will post pictures of my boat shorty.

Have you considered the weight difference?

A 150hp Honda would be no problem - right Reelapeelin?!

Here is a test you could do-

Take a 200 lb (very brave) man and have him sit directly on top of your 150 2 stroke while you do a hole-shot out of the water and venture out into some swells. With this temp modification technically it should perform about the same as the heavier 225 as far as porposing goes.

I know its not a realistic test that that's about what it would be like.

I'm going to have to agree with Pink Jeep.

His boat was a center console not a cuddy like a V21, but that 225 HONDA is ALOT of weight to be hanging off the back. You'll also want to consider he had his transom mounted, and the V21 has a setback built into the hull already adding leverage. As many here have experienced, that setback can make some hulls a real bare to handle due to porposing. These are things to keep in mind. And could you also post pictures of your hull for us, it appears that a V21 was built in 04 but it doesn't resemble the classic V20.

And here is the link to jackman1939's previous post regarding his HONDA 225 experience.

If this is your hull, then disregard my above post. This hull is not the same as our old venerable V20's/V21. It has a lower deadrise to it, more weight, larger fuel tank, and is rated for a large 4 stroke engine. It was offered with a 225 YAMAHA 4 stroke as a factory option.

Once again I agree with Pink Jeep

Thermantor -

more information - I have a trim tab plus four stroke 15HP trolling motor already mounted next to the main OB.

So do you give this idea of replacing my current OB a blessing? Or am I better off keeping my current motor? I am thinking if nothing is broken then why fix (or replace) anything.

I still need to study on how I could post pix of my boat for all to see.

Thanks again.

Thank you guys for your two cents.

I will just go about with my current motor as this will be my 5th season.

About my V21 - I will post pictures for all to see. V21 is a perfect all around fishing machine and I run it with two cannon Mag 10 riggers, depth raider and Lowrance FF. Next month will be the beginning of the steelhead fishing and spring Kings.
