Inboard Transmisson VS I/O outdrive Poll:

[stunod12]

Hi,<br /><br />I am wondering if you boat owners had a choice between a 15 year old inboard *straight drive* or a 15 year old *Outdrive*, which one might hold up better and why?

Straight drive.. Fewer moving parts..

The straight drive.<br />* less moving parts<br />* less maintenance<br />* less parts in the water to corrode

Hi Stunod<br /> This would have to be a case by case decision. Both systems have their strengths and weaknesses. Both systems can be expencive to repair. There are some I/Os that can't be beat for durability. As far as corrosion is concerned that all depends on past maintaince. It is my opinion that both systems are equally prone to corrsion. As far as moving parts go, about equal there too, You still have to count the rudder.

My choice for more than 30 boating years has been the I/O:<br /><br />Better performance (speed/HP, 5-10 mph faster).<br />Better fuel economy (by 10-20%).<br />Better bottom-collision avoidance. (raise drives when in shallow waters)<br />Better manuverability.<br />Better maintainability. (easy to service a stern drive - tough to pull a inboard's transmission)<br /><br />Just sold my 30'1983 with original twin 280 Volvo I/Os and they are probably good for another 20 years. They only took minimum maintenance for over the 20 years (clean zebra mussels, check and change I/O oil, touch up props, replace bellows (twice), annual paint touchup on drives w/epoxy paint, and replace Magnesium anodes every 3 or 4 years. <br /><br />Just sprung for a newer 32' boat, also with twin Volvo I/O. Inboards were also available, but WHY change a good thing ?? I love the Volvo I/Os !!!
