I am looking at a boat with a 2002 MERC 225 3.0L. This 20' will supposedly do 80+ MPH. Is this a good motor choice? Any issues to be concerned with? How about the stock lower unit? Any comments will be appreciated.

I You did not say if it was a EFI or Optimax. Both are dependable motors but the EFI really likes the gasoline.

What kind of boat?? I have an '03 225 EFI and on my Blazer it will only get up to around 76+. 80 plus sounds like a lot unless you are looking at something like an Ally, Bullet, etc.
As mentioned above, the EFI's are very thirsty...but I love mine.

Sorry, I forgot to mention it is EFI. It is on an 02 Bullet XDC. What I was most concerned with is dependability, longevity and the lower unit. There seems to be lots of discussions about changing lower units when prop heights and speeds are high.
I would guess that 80+ on a Bullet is possible, but doubt it will be that much more than 80. Mine has a std lower unit on it and I can't raise it any higher or I lose water pressure. Currently around 1-3/8" below pad. Pretty sure I would be better off and faster if I could get it higher, but I'm stuck for now.
Had mine for about 2 years now (bought boat used) and it's been very reliable. Haven't done anything to it other than normal lube and water pump, and had to change one fuse.
Very dependable motor......I know of many with thousands of hours on them![]()

With your 20' bullet with a sportsmaster lower unit with 1.62 gears you will fish low 80's maybe alittle better and be high 80's and possibly 90 propped right and light![]()

.....If you choose to use a torque master or fleetmaster lower(not recommended) with 1.75 you still may fish at 80 but wont be able to run the big #'s

That would be the "black painted lower unit" that the engine came with (utilizes a standard size propshaft and gears).![]()

What I meant was what is the ratio and type? Are sportmaster, torquemaster and fleetmaster all aftermarket units? This is all new to me.

Sportmaster, Torquemaster and Fleetmaster are all "high-performance Mercury Lower Units".
The standard gearcase is simply a production-line, standard gearcase.
Normally, you'll have a 1.75:1 standard gearcase on your engine. Would be glad to verify what it came with (by serial number).![]()

Is it absolutely necessary to change out the lower unit? It seems that most get changed by guys terying to run at the ultimate top speed with the prop above the pad. If you run a conservative setup, will the stock lower hold up?

I would not recommend running ANY of the earlier "standard" gearcases on this hull.... (this would be any of the gearcases without the low water intakes).
CERTAINLY not at any speed above 75 MPH!![]()

Thanks guys. If I decide to follow through and buy this 02 combo, where is the best place to find a good deal on a quality TM? I think the TM would be best suited to me and the water in the area. Not too many places for me to run 85-90 MPH and if I understand right it will probably launch better with this setup.
Take a look in the Motor Parts forum. You'll commonly find 3L Torquemasters there.![]()
