I got to tell you the longer I have this 25hp the more I'm getting pulled to it because it runs so darn good,but so does my 93. I can definitely tell that the 93 is a bit more worn then the 02 due to how tight everything is on the 02. The original bolts of the 02 were hard to get off because they have never been off ever,once off they went back a bit easier of course. That tells me the lower unit was never taken off. The thermostat bolts have never been removed as well. I just love the look of the 93 better plus I have to tell you there is a major difference in power between them,the 02 just due to it being a 25 has more torque for sure but at wot my 20hp with near 900lbs of weight it hits near 30mph the same as the 25hp so that tells me the 25hp carb for my 93 should do unbelievable wonders in both torque and wot speed. I get almost identical speeds with the 20 and 25hp with near 900lbs of weight which is mind boggling to say the least. I'm quite sure that when I switch the carbs out it will be a well worth it investment at least imo. Yes it will eat a bit more gas than the 20 carb but the power difference should be night and day.
I have to tell you also I'm using royal purple full synthetic tcw3 oil and please understand I am a die hard royal purple user in all my cars and everything and I'm not impressed with their marine oil at all,it smokes like a chimney when it's supposed to smoke almost nill according to their site. Now as far as lubrication I truly believe it's superior to Dino oils but I have 4 gallons of full synthetic tcw 3 Pennzoil and so far from my tests the Pennzoil is far better as far as smokes less and less money. I may just go back to the $12 super tech oil from Walmart if it's going to smoke the same and I know super tech oil is awesome stuff and it has never ever given me any issues for pre mix,in fact just the opposite, it mixes easy and lubricates awesome. I may switch over to amsoil oil at a later time or stick to the full synthetic pennzoil. Now lower unit oil I will stick to royal purple all the way because imo it's superior to all lower unit oils. You can't wash that stuff off your hands no matter what you do,that smell is there even after I wash my hands 5 times,it's got such a strong film that even if water got in my lower unit I would not be scared at all because that stuff is the best,again imo. I'm sure there is other great oils out there but for the little money when broke down I get 3-4 lower unit oil changes for $15 it is well worth it to me for peace of mind, that is only around $4 every 6 months and $8 a yr for peace of mind. Now I can understand if you have a 30hp it can get pricey but if you buy it by the 5 gallons then it's much cheaper. For me my 20hp takes like 10oz give or take a couple Oz so I get roughly 3 changes at $5 a change. Well worth it to me and I know my lower unit gears are protected. When I buy new I will as soon as I take it out of the box replace the factory stuff with the royal purple to. I want my gears fully protected from day one. I think once I use up the 6 gallons of oil I have,then I will evaluate either keeping this motor till I die or selling it for the 20 or 25hp suzuki.
I know I can sell this 93 for well over $2k as I had plenty of people wanting it the short time I had it on Craigslist, people went crazy for this outboard but I just couldn't unload it. I won't find one like this at least here in fl anytime soon again or ever if I wanted another in time. 25hp 2 stroke Yamaha are a dime a dozen here,20/25hp pristine merc 2 stroke is nearly impossible to find in this good of condition. Also when I see an ad that their motor is flawless, then u get there and it's a pos,my flawless and most everyone else's selling outboards is much different. To me pristine is like as new as you can get with like minor scratches or somewhat along those lines.
