recently got a1999 bf50(sold new in 2001)<br />when it was rigged i asked about maintenance<br />as this is the first 4-stroker on the boat.<br /><br />mechanic said change the engine oil and the gear oil once a year(or every 100 hours)<br />and thats it!<br /><br />this seems minimal to me, but maybe he's right ?<br /><br />any tips to keep the motor running long and well ?<br /><br />Thanks
