Thread: New Yamaha 25 vs. 1986 Evinrude 30

Here is my opinion for what it's worth. # 1 seems you have a prop issue on your present motor. Before I spent a lot of money on new motor I woul find a smaller prop for the present motor. That should increase your hole shot and probably increase overall performance. If not and you just want a new motor I would opt for the new light weight 25. Should see better performance from it than the old 30. Especially if it's propped right. I agree with dealer. I would not put a 40 on that light a boat. Especially a tiller steer which I assume you are dealing with. Dosnt sound like you go very far that you would need that much speed. Plus that 25 would be more well suited for trolling on that boat.

I agree with Cray.

The motor rpm's can be adjusted easily at the handle. EFI is standard. It weighs less than 130 lbs. Overall it is just a well thought out motor. It will cost about $4000 for a 20" ES tiller motor.
I visited the local Yamaha dealer today and saw the motor. He told me that the reason my previous 25 Yamaha did so well with the 18' Lund was because that motor was a beast with more displacement cc's, but it was too heavy for small aluminum boats and they were losing market share. Hence the F25.
The next step up for my boat (16 ft Lund) would be a 30 or 40, but they weigh the same, about 214 lbs. He said he thought that was too much weight to put on the back of the boat. He may be right; he may be wrong. I know most would go for the biggest they could put on the boat. I am not inclined that way, as I am almost 76, and have no need or desire to race from brush pile to brush pile. I usually run 2 miles or less and troll quite often. My transom right now has the 30 Evinrude, a 4 Evinrude and a MK trolling motor. That F25 would replace all of that and represent about a 70 lb reduction in stern weight......something I'm concerned about, as I do not see myself losing much weight, particularly after my doctor told me what I have longed to hear for years........weight loss at your age will benefit your joints, but not do much for your general health!!! BTW, except for the joints I have no known medical problems.
Forgot to add that the stern MK would be replaced with one of those fan-dangled remote jobs on the bow.
Part of the fun of fishing and owning a boat is getting the opinions of others, trying one thing, then another and even just thinking about it !!

Thank you for the reply.

I also am attracted to the idle adjustment speed. That is a nice feature that I'm not aware of any other motors in the class have. I was initially attracted to the Tohatsu 25 due to the larger displacement, 3 cylinders, higher end tiller arm, and the fact that tilt and trim is available on the 25hp in the short shaft model. However, the Tohatsu with T/T weighs about 55lbs more than the Yamaha and doesn't have the idle/trolling speed adjustment.

In your research on the Yamaha did you learn anything about he low speed vibrations they seem to have? I read where someone said their new one did vibrate a lot but were told that will go away after break in. But have not read of any confirmation it actually does.

What I have read, and what I have seen, confirm that the is low speed vibration, but it goes away with increased speed. I was told that almost all motors have low speed vibration, but the Yamaha seems more than I have observed.
Thanks to all who have replied.

I can idle my 2015 25 hp Yamaha on a 1648 g 3 jon boat down to 1.4 mph by adjusting the idle screw. Just a FYI. And it runs great.

I have recently purchased a New Yamaha 25hp 4 stroke. I bought it because of Yamaha's reputation of having the smoothest and quietest motor of the 4 strokes. I have run the motor about 10 hours and do not like it. It is about to shake the boat to pieces. It rattles the compartment doors on the boat. I have contacted Yamaha and they tell me that is normal for that motor because of the way its counterbalanced. I say I wasted 4400 dollars. I am probably going to trade it this spring for a Suzuki when I take it back for its 20 hr service. I am very dissatisfied with the motor and Yamaha does not seem to care. Very frustrated.

It is amazing the difference in the Yamaha motors from the lower HP to Higher. I have a 2015 50 HP on my boat... quietest, smoothest motor I’ve ever owned... I have a friend with a 25 on his boat and like previously said, it will vibrate you to death at idol and lower speed.
