Installation Guide

  1. Preparation: Disconnect the battery and ensure the sterndrive is in the fully down position. Relieve any hydraulic pressure in the trim system before proceeding.
  2. Access: Locate the existing hydraulic trim hose connections on your sterndrive unit. You may need to remove engine covers or access panels depending on your boat configuration.
  3. Drain Fluid: Place a drain pan beneath the connections to catch hydraulic fluid. Carefully disconnect the old hose from both the pump and trim cylinder fittings.
  4. Remove Old Hose: Unscrew the fittings and remove the old hydraulic trim hose. Inspect the connection points for any debris or damage.
  5. Clean Connections: Wipe down all fitting threads and sealing surfaces with a clean rag to ensure a proper seal.
  6. Install New Hose: Route the new hydraulic trim hose along the same path as the original. Ensure it is not kinked, twisted, or in contact with sharp edges.
  7. Connect Fittings: Thread the hose fittings into the pump and trim cylinder connections hand-tight first, then tighten with a wrench. Do not over-torque.
  8. Refill Fluid: Fill the hydraulic trim reservoir with the appropriate hydraulic fluid per your engine manufacturer's specifications.
  9. Bleed System: Operate the trim system several times to purge air from the lines. Check fluid level and top off as needed.
  10. Inspect for Leaks: Run the trim system through its full range while monitoring all connections for leaks. Tighten fittings if necessary.
  11. Test Operation: Verify smooth trim operation in both up and down directions. Recheck all connections after the initial test.
  12. Final Check: Reconnect the battery and perform a final inspection of the installation before returning the boat to service.

Troubleshooting & FAQ

Q: How do I confirm this hose fits my engine?
A: Check the compatibility table above for your sterndrive model and year. This hose fits Volvo Penta SX-M, SX-C, and SX-S models from 1987-1993, as well as all OMC COBRA sterndrives from the same period. Note that 1986 models used a different hose with different end angles and are not compatible.

Q: What's the difference between stainless braided and rubber coated versions?
A: Both versions are functionally interchangeable and will work with your system. Stainless braided hoses offer slightly more abrasion resistance, while rubber coated versions provide additional protection against corrosion. Choose based on your preference and installation environment.

Q: What are the signs that my hydraulic trim hose needs replacement?
A: Common failure signs include visible fluid leaks around the hose or fittings, slow or erratic trim operation, low hydraulic fluid levels, visible cracks or fraying in the hose covering, or loss of trim holding power. Replace the hose immediately if any of these symptoms occur.

Q: How often should I replace the hydraulic trim hose?
A: Replace the hose whenever you notice signs of wear, damage, or leakage. Inspect the hose annually as part of your regular maintenance routine, checking for cracks, abrasion, or fluid seepage. In harsh marine environments, more frequent inspection is recommended.

Q: Can I use any type of hydraulic fluid in the trim system?
A: Always use the hydraulic fluid type specified by your engine manufacturer. Using incorrect fluid can damage seals and compromise system performance. Consult your owner's manual for the correct specification.

This book is a must read for anyone trying to understand the role of the US in trade.
Format: Hardcover
Hudson explains US monetary policy from the pre-WWI era to the present day and the points at which it goes through significant changes. He covers the goals of the US at the time, the perspectives of the victims and opponents of these policies and the reasons for changes in monetary policy. I had already read the previous edition but he updates this book to include how the China and Russia are building effective resistance to the machinations of the world bank, IMF, and to the hegemony of the dollar zone in general. Essential reading!

A valuable review of the collapse of the USSR
Format: Kindle
Collapse is a modern review of the fall of the Soviet Union with a skepticism of its inevitability. This review is valuable on its own merits but given recent events of Russia's invasion of the Ukraine it is particularly timely and provides the reader a comprehensive history for which to to think about current events. The book is divided into two sections. The first covers the reform period under Gorbachev which were the seeds the end and the second part which detailed the political events around the collapse of the Soviet Union. It discusses the reform agenda, the power struggles the lack of correspondence between optimistic visions and practical realities involving reform and ultimately the failure of the West in providing any cushions for a viable economic transition at the end. The author starts with the main leader associated with the fall of the USSR, namely Gorbachev. The author starts by highlighting the consensus perspective that the fall of the Soviet Union was an inevitability of the inadequacy of the system to compete in modern times coupled to weakening energy prices that made the state unviable. One could argue with the modernization of the Chinese state, the fall of USSR perhaps was not inevitable had the party been more adaptive to changing conditions. Either way the author believes that such a view is ultimately wrong and the collapse of the union was a direct result of misguided reforms that were counterproductive and accelerated the fall of the regime. The author puts the policy errors squarely at the feet of Gorbachev who he frames as being too focused on theoretical debates rather than focusing on practical realities. The author discusses how Gorbachev's lack of willingness to use force as well as his optimism about the chances for a shared vision by the population led to a fracturing state where a variety of tribal interests started to diverge. The soviet states were not tied to each other tightly through shared ideology or history and so when reforms led to lower living standards and resources had the potential to be divided, the factionalism of the system came to the forefront. Furthermore the lack of willingness to suppress dissent let to a system that ultimately became immobile to competing voices for which none had a solution to the real problems of the system. The author moves on to the fall of the USSR which really started with the Berlin Wall. There were clearly splintering objectives and the population behind the USSR had divergent hopes on the future. Most states claimed desires for democracy but many really were moving to various forms of ethnically based populism. The concessions made by the USSR on Germany are argued to show the naivety of Gorbachev who was trading Soviet influence for the hope that his signals would be taken well in the West and reciprocated with good will and eventual aid. The sequential failing of the state stemmed from the conflicting power from the formation of democratic parties to compete with the Soviet legislature; the clear separation of powers became ambiguous and ultimately this incoherence of the system led to a partial lost confidence in Gorbachev and a temporary coup. The democratic advocates like Yeltsin then agreed to multiple side deals in which the USSR was carved up along vaguely tribal lines in a hasty fashion that left lingering problems for the following generation. The chaos of reform and decaying control led to a failing state that fractured chaotically and became impossible to salvage once the snowballing began. Collapse is a detailed historical overview of the last decade of the USSR with a focus on the failure of Gorbachev. It discusses the political and economic challenges of the state that led to its collapse but focuses on the failure of leadership that was the root cause from the author's perspective. It is hard to argue that exogenous events didnt put substantial pressure on the regime such that it might have been destined to fail but the authors arguments that the reforms were ineffective are hard to argue with. Furthermore for there to have been a realistic chance of a change in economic model substantial aid would have been required and the idea that the Washington consensus was a sufficient laundry list to lead the USSR into the modern economic world is completely ludicrous. One is reminded of the politics behind economic bodies like the IMF despite the claims to be independent and objective analysis on best practices. As a consequence of the unrealistic idealism of the time and the subsequence tragic failure of following that idealism to a disorganized state we now have substantial lingering frictions that are impossible to heal. Collapse is highly worthwhile read that is filled with details and certainly relevant today.
