Marine Diesel Repair: Perkins 4.236 Starter Removal, Rebuild and Re-installation

Perkins 4.236 Starter Removal

We recently attempted to start the 85-hp Perkins 4.236 Marine Diesel Engine on Banjo as directed by our hired marine diesel mechanic, Chuck Courtney. (EDIT: 2019Jun25: I was directed to over-crank the engine but not let it start.  Unfortunately, we have since learned this is never a recommended practice, but i didnt know it at the time and followed his instruction.  I was instructed to over-crank anywhere between 7-10 times.  See THIS POST for more information on the full damages incurred and the out-of-pocket cost to fix.) As the engine…

Three Boat Flotilla, 1 Mantus Anchor, and 30 Knots of wind

Three boats, One Mantus

Yesterday, we had a couple friends come into the cove to visit.  The conditions were calm, so our friends rafted up to Banjo creating a cool three boat flotilla to spend a nice Saturday night.  Around 04:30 this morning, we awoke to significant wind gusts only to remember that we were the only boat anchored of the three.  The wind gusts were in the low-mid 30-knot range.  We found ourselves in the situation of a three boat flotilla all sharing one Mantus anchor. The specifics of the three boats were…

Perkins 4.236 Engine Repair: Raw Water Pump

Perkins 4.236 Marine Engine Raw Water Pump installation

I received a call from Chuck first thing this morning. He had been thinking about our engine and the possible locations where water could get into the crankcase.  Although the most obvious answer to the problem is a blown head gasket, Chuck made a recommendation to check our raw water pump.  By ruling out the raw water pump first, we could potentially avoid the costly head gasket replacement. What is a Raw Water Pump The raw water pump on Banjo is responsible for pulling sea water into the engine as…

Perkins 4.236 Engine Repair: Water in Oil

Background A few weeks ago before Hurricane Florence hit New Bern, we had a problem starting our Perkins 4.236 Engine.  The starter would barely turn over and then stop.  I’m learning, but I am not a good engine guy yet, but I am slowly learning how to do some basic Perkins 4.236 Engine Repair myself.  We had a friend look at it and they noticed that we had more oil on the dipstick than usual.  A LOT more. A couple of people looked at it and the proposal was given…

Our Boat Refrigeration Problem: Part 1

We have a dilemma.  Since we have been on the hook, we have found that we seem to have ample electrical power, except when it comes to refrigeration.  For the past few weeks, we have avoided putting our battery energy into refrigeration.  Banjo came to us with a SeaFrost DC5000 12V Refrigeration System.  The system consists of two cold pates; one for the freezer compartment and one for our double refrigerator compartment.  However, the compressor for the system draws 40 amps.  That’s right, true believers, we said FORTY amps.  Also,…
