Why not go with the Merc Verado 350hp for the 80's - 90's era Mako 25 CC.
Go to utube and you can see this new 350hp in action......actually triples on a Fountain 38 CC at take off, cruising at 55mph, and WOT just under 80 mph. Engine sounds quiet and strong.
This 350hp matches up to the 25's maximum hp rating, and likely weigh less than two 175's....... |

I personally would wait for at least a 450! But seriously, how fast do you need to go, particulary with the cost of fuel ever increasing. It must be nice to have an unlimited budget and an understanding wife! I feel the need for speed!!!  |

"To stay on subject, a friend has a 42 Yellowfin waiting on 4 350hp Verados. Word is the engines won't be delivered until the end of the summer."
Who's buying a Yellowfin with quad 350's? |

Not to derail any thread but I don't believe any of this.First hand expierance says your not going to get that mileage. To many variables.
1st,what were the seas.
2nd,what is the weight ie, fuel,gear,people,etc.
3rd, even if you get 1.5mpg with a 325 gal tank give you a math range of 487 miles. With a head sea of 4' to 6' you'll be lucky to get a 350 mile range. Out of Cape Canaveral to the Yellowfin Tuna grounds it's 120 miles one way!. |

I pulled this from another thread...
Here is a quote from the article in May 8 2008's The Fisherman NJ and Del Bay edition.
"A trio of 350 SCI Verados were recently tetsed on a Fountain 38 CC Tournament Edition,spinning four-blade Merx Racing lab-finished Bravo 1 stainless steel (15.25x28) props. This thoroughbred was actually planing along at 2,100rpm powered by three 350 Verados-at 4,000 revs, this platform hit 44mph while drinking fuel at only 29.7 gph for an incredible optimum fuel efficinciency of 1.6mpg.
The triple Verado 350's also produced 1.4mpg @3,000 rpm netting 29mph and 1.4mpg at 5,000 rpm where this power package pushed the 38 Fountain CC along at 55mph, so there is an incredibly wide band of fuel-efficient crusing speeds that range from 29 to 55mph with little or no penalty in range or running costs. Since these 350SCi Verado's are deisgned to redline a bit higher than their sisters, they pushed the Founatin to an impressive top speed of 80mph @6,800rpm."
The article goes on to say it's slated to go into full production in October of 2008. Also states that the msrp for the 350's is expected to be $28,813 for the 20" shaft, and $29,063 for the 25" shaft and $28,313 for the 30".
Also, the Gen II Verados are more efficient at the upper (>4,500) rpm range than Gen I's. I've yet to see a performance report where a F350 burns less fuel than any 275/300 4S, Opti, or etec at cruise - not a slam, it's just a big brute. Great for heavy double, or tripple applications. I haven't seen a report on a single application where I would choose it over a 300V, Opti, or e-tec though for mid-range speed & efficiency.
I'd agree though - twin 175's e-tec or opti's for that hull. |

The Verados come with a standard 3 year warranty and they are giving away 2 extra years right now. 5 Years warranty

Just got back from the bahamas on another good fishing trip... the merc verados still suck!!! we had the end up popping the cowling off to start it... motor is new and rusted very bad and this rig is taken care of... the guy that even wipes down the engines just looks crosseyed at ya and says he misses the yamahas... fuel burn on the 32' intrepid with the mercs is only at best 1.35 mpg ...steering still sings ALL the time.. (<<~~~ fishing is supposed to be peacefull right???) anyway 1 more rat 220 lb blue some nice dolphin and yellowfins made a great trip we also cruised by a neat whale shark..made my day! The same intrepid with yama 350's was 1.68 mpg had 3 more people on board and went about 11 knots faster.. those mercs also have no warrantee after ya buy them...OPPPS my bad ...only 1 year!! merc needs to take care of corrosion before I'd smile at them any..! |

I hope that Yellowfin has one big ass fuel tank. I'm thinking maybe a 1/4mile per gal. |

the gear case on the 300 is a big improvement too |

I've asked the same question to a few "experts". The 250 HO is pushing ~275hp from the 3.4 liter block. The foot design is set up for go fast bass and bay boats, mostly in a single application. The 300 hp is a true 300 hp on the 3.4 liter block that is designed with the beefed up foot for offshore twin/triple applications on big machines. Design application also dictates the performance (GPH) curves.
To stay on subject, a friend has a 42 Yellowfin waiting on 4 350hp Verados. Word is the engines won't be delivered until the end of the summer. |

The price difference can't be much and twins are better when you want to run offshore. On top of that, I'd rather have the simple motor ten years down the road. It will be interesting when you hear about some guy who needs to rebuild supercharger, pistons, etc. Cha-Ching! Cha-Ching! |

So then I guess the E-TEC doesn't have a direct injection fuel system under MORE than 600 PSI and a COMPUTER that controls it. Just because it's a two stroke don't go thinkin' it's your daddy's engine.

I was definitely not comparing the E-tec 300 to the Verado 350. I wouldn't even consider the Verado unless I had endless cash to buy new ones every time they took a dump. I guess we'll see once they start getting some hours on them. I also think they are way too heavy for Older Makos. I was just picturing in my head the smaller sized E-tec 350 (which it will undoubtedly be) pulling alongside an F350 equipped baot with that massive cowling on top of it and blowing it's doors off with the impressive hole shot all of the E-tecs to date have been known to have. You can't argue the difference in torque a 2-stroke has over a 4-stroke when it's 2 power strokes to every 1, especially at low end.
Just think what kind of power you would have if the supercharger gave out and you are limping home with a very low compression engine with the timing offset to deal with the supercharger. You might as well be using a kicker turning an oversized wheel. |

The Merc 350hp outboard specifically does NOT clunk in and out of gear, and is very quiet for its power output.
Video drag on utube also showed it out performing the Yami 350 in drag race............of course, complete match up could not be verified.
I believe the Merc 350 would walk away from the Etec 300, but that's just based on my perception of both engine performances. |

The E-tec 350 is more than just a rumor as is the Yamaha F400.
Anytime you supercharge anything you are taking chances. First you have to lower compression to compensate for the forced air which, in effect, increases the compression yield. Also, you've added another belt driven component to the mix and another possible weak link. Add the needed 93 Octane and you've got yourself one expensive machine to operate. Whoever said they were noisier is wrong. They are correct about the fuel consumption at high RPM, however, but who runs that long at that level and overall they are the most fuel efficient motors under average use and the midrange response is amazing.
That being said, I was raised on power boats and sailboats and any old salt will tell you the less parts there are the less to break or go wrong. The E-tec with it's small parts list and lower weight, coupled with it emission rating and relatively low noise appears to be the best bet if you consider all the factors and average them out. I'm always hearing my buddies bitch about the the cost of their services on their 4 strokes and some of them went with lower power to try to keep the weight down. Well, they've got nothing for a hole shot compared to the E-tec and their wallets are still recovering.
I'd like to say that it's 6 of one, half a dozen of the other but it's not. Wait for the E-tec 350 to come out and pull alongside one of those monster F350 driven boats and leave them in your wake. |

a pair of 225 ETEC HOs seem to me to be the hot ticket, on a new transom of course |

Something in my head says a high blown outboard is going to be trouble maintenance-wise in the long run. That and from everything I've seen they're not exactly misers on fuel.
300 zuke or etec is what I'd look at. Actually, wouldnt be surprised to see a 350 etec in the near future. |

all the 350s need special steering... make noise while steering... suck fuel for weight... sound like mac trucks when shifting..things to think about.. the merc warrantee is expensive so is yama...needs special (tune - ing).. without good gas the 92 octane 275 I run still detune themselves on the o2 sensors.. |

I personally think the 350 Vrod will outperform the 300 E-Tec on a 25', but the drawbacks for us weekend boaters would burst my bubble. The 350 Vrod is a tuned up 300 Vrod that is sold through Mercury Racing. They have increased the rev limiter from 6000(?) to 6800(?), the Vrods are known to drop off in gph performance in comparison to other similar outboards above 4500 rpm, and only a 1 year limited warranty is offered for the 350.
Having said that, I believe a more practical 350 hp from Merc is on it's way in the near future.
