Default Verado v yamaha

Building a 36invincible trying to decide between trip merc 300 v8 v Yamaha 300. Mostly running 100miles offshore, so not looking for max speed. Looking for best fuel economy at mid range 35-40kts. Also considering merc 350ís. Thx for all input

Had 300 Yamahas on my Regulator for 8 years with no issue and now on my Freeman and still no issues ....no experience with Mercs.

The Mercury V8s will be the most fuel efficient of those 3 choices. The most direct comparison I have personally experienced was on a 32YF that we removed Yamaha 300s and repowered it with V8 Mercurys. Our customer was able to run his ‘normal’ offshore trip before the hurricanes hit south LA. The Yamahas would average around 1mpg while the Mercurys were averaging 1.6mpg. They returned with over 50 more gallons of fuel than they would’ve with the Yamahas. His friend that owns a 32YF with 350 Verados was also on the trip and they make the same run regularly. His boat typically burned 20-25 gallons less than the Yamahas on the same trip.

That can be said about any motor. I once had a 200 Yamaha go boom. Luck of the draw.

Proven Yamaha 300’s? See making oil and rumors a about metallurgy issues.

Merc all the way. You can’t go wrong with the v8’s or 350’s. Mine has been flawless, quite and simply perfect.

Read all you want on the internet but an f300 yam is as good of an engine that has ever been built. The 300 v8 nercs are certainly the new sexy girl at school and seem to be just fine but you absolutely can not beat a 300 yam for reliability. I run a triple set on a 35ft cc typical run 20 to 30 mi offshore ill see about 1 4 or so up to 40mph loaded for overnight trip to the rigs with motors running nonstop I get a tick over 1mpg key to key. Id buy mercs in a heartbeat but the v8s don't have the longevity proven just yet.

No you are absolutely not right about this.

What I said is Iíve been on two boats that had mercurys fail and none with Yamahas. Maybe you can say that about any engine, but donít correct me about my experience, post your own if you want but donít copy and correct me.

Yamaha 300 - proven reliable
verado 350 - proven reliable, more efficient and faster than above
verado 300 v8 - more efficient and better with regular heavy loads than both above

I'm a Yamaha guy but the new Mercury V8's are one impressive motor. I don't know if Merc does extended warranties like Yamaha does but I'd buy it in a heartbeat with an extended warranty.

Own both. 300 Verados and F300

both trouble free.

If you get Mercs, get white

I'd go with Merc 300 V8's if your looking for fuel economy. Verado 350's/400's are not far behind either. On another note, 300 V8 can run on 87 Octane.

Merc 300 V8 87 Octance
Verado 350/400's need 91-93 Octane

The only boat Iíve ever been stranded on was powered by twin Yamahas. Lost a powerhead on the way out and then lost a lower unit on the way in. Never in a Mercury powered boat. Real world experience.

It would be interesting to get input from Invincible, or have them put you in touch w/customers w/the motor set-ups you are considering.
