Offshore 535 and Johnson V6 GT150

[jasper2447]

Hi everyone<br /><br />I've been absent from I-boats forums for a while now - no boat - but am thinking of buying rather a nice classic - an Offshore 535 by Isaac Workboats of UK. Does anyone know anything odf this hdesign, as it was exported to the USA by Isaac Workboats?<br /><br />It's powered by a contemporary Johnson V6 150GT and I'm wondering if anyone has any experience of these engines and what points to look out for when buying?<br /><br />Are they reliable ?? Economical ?? What about spares ?? or would I be better forgetting about authenticity and investing in a new Mariner of the same HP ?? <br /><br />John
