I have a 1973 John Allmand 23 foot boat with twin Volvo AQ-130C engines mated to two 270 outdrives. Both engines are frozen up. Does anyone know what other engines besides the 4cyl OHC volvo engines can be mouted to these outdrives?
 
You could mate a pair of Chevy 2.5 or 3.0 liter 4-bangers but you'd a) have to get bellhousing / tailshaft assemblies off a V6 or V8 Volvo / Chevy installation, then you'd have to have some custom exhaust pipes welded up 'cuz the Chevy has the exhaust on the "wrong" side from the Volvo. I'm seriously looking into engineering a swap of this kind...it would provide the reliability of the Volvo Aquamatic drive with the simplicity of the GM engine.
