all honesty needed! mercury(yamaha) 90hp 4 stroke performance

[spareparts]

I work on few HPDI's. Like whats been previously said, the bigger engines(250-300) were the ones that give issues. The smaller ones seem to hold up well. But keep in mind, they are exspensive to run. Plugs are $$$ just like any DFI, the $300 high pressure fuel filter is now down to $90 and Yamaha DFI oil is expensive. Savings in fuel get eaten up by oil cost. I think they only offer the 150 HPDI now for the bass boat market. You don't see that many around any more. If you have high pressure fuel pump issues, its big money to have it rebuilt, even bigger to have it replaced, like over $2000 for some models. Like most new engines, they are intolerant of crappy fuel, but HPDIs are even more so. You don't see many getting rebuilt due to the preventative expenses to insure they stay together. Good motors, but its a gamble with high stakes

For 1500 it's a good price. Just run some clean oil. That 2m is very dirty and will cause carbon build up on a DI engine.

Looks like that 4.5 hp Merc on the dining room table is the way to go...

The guy is having the entire fuel system gone thru and all fuel and vst filters replace and injectors done and new water pump. It is a 25" shaft so i will be building my transom up for now. And doung a solid transom probally after the fall. Motor comes with all gauges,harneses,oil tank and controls for 3500.00. Its a 2004 with 390 hours on it.

For $3500(I think the $1500 was a different engine) it's a good price, but personnally I would pass. When they're running, they run great. BUT just one repair can turn one into a parts motor in a hurry. With DFI engines what would normally be a simple repair can cost as much as another engine of the same vintage would. Then figure in maintence costs along with the need for a dealer to do electrical repairs, they can get pretty pricey. I considered a DFI when I had my HYDRA-SPORTS for the fuel savings, until I figured 1 or 2 dealer repairs in. Then all of the sudden my old carbed thirsty 2 smoke sounded pretty dang good. Yep I used 20-30% more fuel than a DFI would have, but I could do any repair it needed, and parts were easy and cheap to come by.

Check it for corrosion CLOSELY! Suzuki's are KNOWN for corrosion issues. I love SUZUKI outboards, but I also know you have to watch for corrosion with them. I know Rm likes his JOHNZUKI on his V-20.

Yeah, my buddies Suzuki 140 has corroded badly. Just broke two bolts holding the water pump housing, and two holding the foot. Not to mention the corrosion all over the power head.
