Engine Repowering
Engine Repowering and Exhausts

Repowering

Bayside Diesel repowers many engines every year with a satisfied customer base that has grown substantially by word of mouth alone. Our reputation for quality service and follow up makes us the best choice for such an important task.
 

Custom Exhausts

Bayside has earned a prominent position as a premier custom fabricator of stainless steel and steel exhaust systems for marine applications of all sizes. While repowering, we often have to retrofit custom exhausts, which we machine ourselves to guarantee a perfect fit.
Due to the overwhelming response to our custom exhausts, we do not promote this service unless it is a part of a repowering project. The effort required to simply assess the specifications for a custom exhaust make it fairly cost-prohibitive to perform on its own.

D.I.Y. Maintenance

Checking the Intake and Exhaust System

Step One

Intake Filter - Remove the intake filter and check the condition of the element. If it's dirty, clean or replace it. If no filter is fitted, check inside the inlet manifold for anything that may have inadvertently been sucked in. Excessive oil on the filter or inside the inlet manifold suggests worn piston rings and cylinders are causing high crankcase pressure. We sell a number filters every year.

 

Step Two

Crankcase Breather - Remove the hose that connects to the valve cover and check for blockages. 

Step Three

Exhaust Manifold - Check the tightness of the attachment nuts and bolts, especially on engines which have heavy manifolds that incorporate header tanks and heat exchangers. Leaking manifold gaskets are the first signs of loosening. 

Step Four

Exhaust Injection Elbow - Salt or corrosion products indicate a leak caused by severe corrosion. First indications are usually small pin-prick sized holes adjacent to the point where raw water is injected into the elbow. Soot deposits by the mounting flange indicate a loose joint or gasket failure. Check tightness of attachment bolts which loosen through high temperature and settling of thick gaskets. Remove and inspect them internally every two seasons. 

Step Five

Hose Clamps - Inspect for corrosion and cracking. Exhaust hose should always be double-clamped throughout its length. Clamps are cheap and easy to replace - our best-selling items. 

Step Six

Lift Box/Muffler - Metal mufflers, even stainless, suffer from corrosion. Plastic lift boxes and mufflers suffer from split welds mostly by over-tightening exhaust hose clamps. Glass fiber boxes are usually maintenance free and provide long service. 

Step Seven

Exhaust Hose - Check for cracking, softness, delamination, kinking and corrosion of the reinforcing wire. Hoses are one of our best-sellers.
