If you are looking for an engine for your boat, have you considered marinising one yourself?
There are now many "bolt on" marinisation parts for a range of well known vehicle engines. Most can be easily converted for use in a boat. We can help you with heat exchangers and the heat exchanger manifold. There are various options available by Bowman or Seaflow, from combined heat exchanger manifolds, keel cooled manifolds and water cooled manifolds.
For certain engines we offer special thermostat housings that line up with the exhaust manifold outlets with minimum plumbing.
Polar Engineering ceased trading in December 2004. Certain exhaust manifolds from their range have been purchased, reworked and included in the Bowman range. Please contact us if the exhaust manifold you need is not listed, and we will try to help you.
