I dont know about zukies but I see a lot of them and they seem to have an excellent reputation from pretty seasoned captains who are out 250 days a year or more. The sea tow and TowBoat US guys here in Beaufort run the piss out of them and swear by em. On the other hand if the REQUIRED DEALER maintenance is anything like some of the others then it may need a second look..An old guy across the creek asked me to pick up and tow his boat from the dealer as he has trouble backing up his truck( he is 75) and I have to say I was AMAZED at the bill. The motor is a 2004 Yammie 225 and just for an oil change it was $178.00 and I wont tell you what the valve adjustment cost $$$$$$$..I was also amazed to see his warranty book with maintenance receipts for what its cost him so far just to run out a few times a year for flounder. And to add insult to injury the dealer talked him into an extended warranty which DOES NOT cover this kind of ROUTINE maintenance...The motors are not the issue here and can probably get along fine without all the required check ups etc. its the greedy dealers but thats just my opinion...Frank
