Question on boosting hp

[tucke87]

I have a 1987 19ft sea sprite bow rider. It is a v hull. The motor is a mercruiser model 470 170hp in\outboard. The motor was rebuilt about a year ago. Is there any performance parts I can put into action on this boat to get more speed. Any help is greatly appreciated. Thanks<br /><br />Eric

Sounds to me like an engine question.

This subject turns up now and then.<br /><br />Short version of answer is 'If you want a more powerful engine, buy a more powerful engine'.<br /><br />The sea is not the right place for experiments. One sure thing if you fit performance parts, is that your engines' longlasting abilities suffers.<br /><br />If you're 170'er had a bunch of horses laying around in there which could be activated easy or 'for free', I'm pretty sure Kieckhafer would have done that..

Tucke87,<br /><br />That same basic engine was later offered as a 185. I believe the major difference was the carb./intake manifold. <br /><br />That engine is basically 1/2 of a Ford 460 cid. engine. All the internals, except the crank and block, are stock issue Ford 460.<br /><br />Anything you can do to make it breathe beter will help.
