Ok,<br />I had one shop tell me that a total rebuild of my Merc 135 could cost as much as $3 or $4000 dollars. OUCH!!!! I see boats listed in classified ads like my Sea Ray for $5,000 complete.(it's an older Seville bowrider).<br />Does anybody have an idea of what I should expect to pay for this rebuild? Is it worth doing? Yes we like the boat, but it surely hasn't been trouble-free. Overheating problems, prop ventilation problems, control boxes going, and other stuff that could be normal. I just am not sure I want to sink (no pun intended) $3000 dollars into a boat I can replace for $5000. And if I replace it, what can I sell a 1988 Sea Ray 18' outboard for with a sick motor? A boat that is in otherwise very good condition? <br />All advice is welcome!! <br /><br />thanks as always, Dutch<br />
